第二组 12题 单选题
1. What is the total price of a UK basket of goods (in £)?
A. 8.05 B. 2.55 C. 9.50 D. 8.25 E. 7.05 F. 5.25
答案解析:A
In order to answer this question we need to sum up the prices of all five products to arrive at the
total price of a basket of goods in the UK:1.25+1.5+1.6+2.5+1.2=8.05
2.How much more or less does Milk cost in the UK compared to Sweden (in £ ) ?
A. 1.20 more B. 0.20 less C. 0.10 less D. 0.10 more E. 0.20 less F. 1.20 less
答案解析:D
The price of Milk in the UK is: 1.6 while the price of Milk in Sweden is: 1.80.
Since we are asked to compare the two prices using the GBP, we need to convert the Euro
currency into GBP by dividing the cost of Swedish Milk by 1.2 (exchange rates are mentioned
below the table): 1.8/1.2= 1.5.
So, Milk in the UK costs 0.10 more than Milk in Sweden.
3. Which product/s has the same price in Sweden and the UK?
A. Eggs B. Oil C. Bread,Eggs D. Milk,Eggs E. Bread F. Oil,Bread
答案解析:C
In order to compare the different prices, we will need to convert Swedish currency (Euro) into
British currency (GBP) or vice versa.
Let us convert GBP into Euro as it seems slightly easier to multiply the currency by
1.2(GBP→Euro) instead of dividing it (Euro→GBP).
UK: Bread: 1.25*1.2=1.5
Butter:1.5*1.2=1.8Milk:1.6*1.2=1.92
Eqqs: 2.5*1.2=3.00
4. How much will an adult ticket to the Guggenheim museum cost in GBP?
A. 14.3 B. 22 C. 16.72 D. 33.8 E. 28.9 F. 12.0
答案解析:A
An adult ticket to the Guggenheim costs 22 Dollars. In order to convert this price to GBP we need
to look at the exchange rate table.
1 Dollar, according to the exchange table, equals 0.65 GBP. Therefore, 22 Dollars equal: 22*0.65=
14.3 GBP.
5. The adult entrance fee to the Louvre equals what percentage of the adult entrance fee to the
Madam Tossauds?
A. 84.21% B. 41.60% C. 64.00% D. 72.72% E. 48.64% F. 55.00%
答案解析:E
Since the entrance prices to the Louvre are presented in a dfferent currency than the entrance
prices to Madam Tossauds, we will need to convert one type of currency into the other type in
order to answer this question.
The exchange rate of one Euro to the GBP is: 0.76.
Therefore, an adult entrance fee to the L ouver in GBP is: 16 *0.76= 12.16.
An adult entrance fee to Madam Tossauds is: 25.
The relative price of an adult entrance to the Louvre compared to an adult entrance fee to
Madam Tossauds is 12.16/25.
In other words an adult ticket to the Louvre equals 48.64% of the entrance fee to
6. How much will a family of two adults, one Student and one Senior pay when entering the
Guggenheim (in £)?
A. 38.35 B. 52.65 C. 81 D. 44.84 E. 50.7 F. 40.05
答案解析:B
An adult entrance to the Guggenheim costs: 22.A student entrance to the Guggenheim costs: 19.
A senior entrance to the Guggenheim costs: 18.
Two adults, one student and one senior will pay together: 22*2 +19 +18= 81.
Now all that is left is to convert Dollars into GBP using the exchange table provided: 81 *
0.65= 52.65.
7.The price of an e-book version of " It's All Good" equals what percentage of the price of the
printed copy version of the same book?
A. 10% B. 43% C. 25% D. 20% E. 19% F. 38%
答案解析:B
The printed copy of the book "It's All Good" costs 22 while the e-book costs 9.50.
9.50 out of 22 equals 9.50/22* 100= 43%
8. How much is the total number of printed books sold per week more or less than the total
number of e books sold per week?
A. 1950 more B. 1850 less C. 1750 more D. 1750 less E. 1850 more F. 1950 less
答案解析:A
The total number of printed copies sold in a week is:
1250+2500+1780+ 1800+2340+1330= 11,000.
The total number of e-books sold in a week is:
1500+ 1050+1670+ 1700+ 1200+ 1930=9050.
The difference between the total number of printed copies and the total number of e-books sold
is: 11 ,000-9050= 1950 (more printed copies).
9. Which book sold the highest number of copies (printed and e books combined)?
A. "It's All Good" B. "The FastDiet" C. "Daring Greatly" D. "Life Code"
E. "The Key Is Love" F. "One Thing"
答案解析:B
Since all the books seem to sell similar numbers of copies when combining the printed copies
and e-book sales, we have no choice but to carefully (and quickly) calculate the total number ofcopies sold for each book:
"I's AII good"- 1250+ 1500= 2750
"The FastDiet" -2500+1050= 3550
"Daring Greatly"-1780+1670= 3450
"Life Code"-1800+ 1700= 3500
"The Key Is Love" -2340+1200= 3540
"One Thing"-1330+1930= 3260
10. How many Defective bottles of Merlot were produced this month?
A. 1660 B. 1440 C. 1600 D. 1560 E. 1200 F. 1180
答案解析:B
Total number of Merlot bottles produced: 9000.
16% of them were defective.
Therefore, 9000* 0.16= 1440 defective Merlot bottles were produced this month.
11. Which type of wine had the lowest number of defective units?
A. Merlot B. Syrah C. Rose D. Chianti E. Shiraz F. Moscato
答案解析:C
Instead of calculating the number of defective botles for each wine type, we can glance quickly
at the data to identify the types of wine which have a low percentage of defective bottles and a
low number of total units produced.
Rose wine has the lowest percentage of defective bottles. In addition this type of wine has a
fairly low number of bottles produced in total.
Both Chianti and Shiraz have the second lowest percentage of defective bottles (13%),but since
the total number of Shiraz bottles produced is higher than the total number of Chianti units
produced, Shiraz can be eliminated.
Thus, we are left to deliberate between Rose and Chianti (note that although Moscato wine has
the lowest number of bottles produced in total, the percentage of defective bottles is the
highest, and so we are able to eliminate this possibility).
Rose: 7600*0.07= 532
Chianti:5500*0.13= 71512. What will be the total revenue of selling all non-defective Moscato units?
A. 59,771.25 B. 77,625 C. 17,077.5 D. 68,310 E. 60,547.5 F. 21 ,643.75
答案解析:E
First we must calculate the total number of non-defective Moscato wine products:
Total number of bottles: 6750. Percent defective: 22%
Total number of non-defective bottles: 6750 * 0.78= 5265.
Now all that is left is to multiply the total number of non-defective bottles by the price of one
bottle to arrive at the correct answer: 11.5 *5265= 60,547.5

4. How long does it take the quickest bus to get from Leigh bus station to Piccadilly gardens?
A. 79 minutes B. 65 minutes C. 53 minutes D. 55 minutes E. 63 minutes F. 48
minutes
答案解析:C
It is easiest to examine each bus by asking the question:
"is the bus joumney more or less than an hour?"
With this question in mind, going over the three bus routes, we can quickly identify that the only
bus than goes from Leigh bus station to Piccadilly gardens in under an hour is: line 26. Now all
that is left to do is calculate the exact travel time by deducing the hour of departure from the
hour of arival at the destination: 05:58-05:05= 0:53 (minutes).
5.If a senior citizen were to buy a daily bus pass, how many bus rides would he need to take that
day in order for it to be worthwhile?
A. 1 bus ride B. 2 bus rides C. 3 bus rides D. 4 bus rides E. 5 bus rides F. 6 bus
rides
答案解析:E
The cost of a daily buss pass is 6.00.
The cost of one bus ride is 2.80, but keep in mind that senior citizens are entitled to 50% off the
cost of a single bus ride.
Therefore the cost of a single senior bus rideis: 2.80*0.5= 1.40.
Now all that is left to ask is: 'how many single bus rides can be bought with 6.00'?
The answer is 4 (6.00/1 .40).
However, for the daily bus pass to be worthwhile for a senior citizen he must go on at least 5
single bus rides.6. The time it takes bus 12 to travel from Swinton to Piccadilly gardens equals what percentage
of the total traveling time of that bus?
A. 21% B. 9% C. 34% D. 39% E. 24% F. 10%
答案解析:C
Bus 12 leaves Swinton at 06:52 and arrives in Piccadilly gardens at 07:19. This route takes the
bus 27 minutes.
The total travel time of bus 12 is: 1 hour and 19 minutes (the bus leaves Leigh bus station at
06:00 arriving in Piccadily gardens at 07:19). 1 hour and 19 minutes equal 79 minutes.
So, the relative time it take the bus to go from Swinton to Piccadilly gardens compared to the
total travel time for that bus is: 27/79 = 34%.
7. How much money does an upper class family spend a month?
A. 13,055 B. 8,925 C. 9,255 D. 10,900 E. 11 ,000
答案解析:A
According to the table, there are 4 categories of expenses: housing, car, food and "other".
In order to calculate how much money an upper class family spends a month we need to sum up
their expenses in all four categories:
Housing- 5100 ; Car- 1900; Food- 5125 ; Other- 930.
The total monthly expenses of an upper class family are:5100+1900+5125+930=13,055
8. Among lower class families, what is the percent of expenses aloted for housing expenses, if
the family's income is 16K?
A. 2% B. 20% C. 2.5% D. 25% E. 2.2% F. 22%
答案解析:B
Lower class families spend 3300 on housing expenses, which are approximately a fifth of a poor
familys income: 3300/16,000= 0.20= 20%
9. What are the average monthly food expenses across economical categories?
A. 2175 B. 3950 C. 1533 D. 4355 E. 3275 F. 2375
答案解析:F
We are asked to calculate the average monthly food expenses. In order to do that, we will firstneed to sum up all monthly food expenses for the three different economical classes and then
divide the result by the number of social classes (3) to arrive at the requested average:
Lower class Food expenses: 780
Middle class Food expenses: 1220
Upper class Food expenses: 5125
Average monthly food expenses across economical classes: (780+1220+5125)/3=2375
10. What is the women's average score on all three tests across age groups?
A. 104.5 B. 104.0 C. 95.0 D. 96.6 E. 100.0 F. 101.3
答案解析:C
There are a number of ways to calculate this average:
1. Calculate the average score of all three tests in each age category (Young/0ld) and then
calculate the average score across categories.
2. Calculate the average score of each test across age categories(young/old)and then calculate
the average score across the three tests.
3. Sum up all the scores of each test in each category and then divide the sum by the total
number of tests in both category (6).
The third option is the quickest method (as it requires only one calculator operation) providing
you are able to correctly identify that you are calculating the average score across six different
tests and categories.
The calculation is: (103+98+106+90+92+81)/6= 95.
11. In the accuracy test, what is the ratio between the difference in men and women's
scores in the young category and the difference in men and women's scores in the old
category?
A. 9:10 B. 7:6 C. 1:1 D. 8:7 E. 9:7 F. 12:11
答案解析:C
In the Accuracy test, the difference between men and women's scores in the young category is:
98-93= 5
In the Accuracy test, the difference between men and women's scores in the old category is: 92-
87= 5
Therefore, the ratio between the differences in men and women's scores in each age category is:
5:5.Divided by a common denominator (5), we arrive at a ratio of: 1:1
12. What is the percentage score of young women on the Speed test?
A. 70% B. 56% C. 106% D. 74% E. 63% F. 17%
答案解析:B
The percentage score of a test is calculated by dividing the number of points received by the
total number of points available on the test.
Keep in mind that the range of scores on the test is 50-150.
In order to make things easier, we can treat the score 50 as zero and the score 150 as 100,
meaning there are 100 points available to receive on the test.
The young women score is 106, which is 56 points above the " zero" point.
Now all is left to do is calculate 56 points out of 100 available points to arrive at a result of 56%

第四组 12题 单选题
1.At what hour is the percentage of vacant seats the greatest?
A. 7:00 B. 8:00 C. 12:00 D. 17:00 E. 21:00 F. 12:00 and 17:00
答案解析:D
In order to eliminate some of the answer choices we can try and locate the train times in which
the percentage of vacant seats was greater than 10% by using the" 10% method" - in order to
estimate 10% of a 3 digit number all we have to do is eliminate the unit digit in each number. For
example: 10% of 300 seats are 30.
Using this method we can quickly identify that at 8:00, 12:00 and 17:00 the percentage of vacant
seats was greater than 10%.
Moreover, at 17:00 the number of vacant seats is 3 times greater than 20 (which is the number
of vacant seats that account for 10% of the total number of seats on the train).
As opposed to the 12:00 train and the 8:00 in which the proportion between the total number of
vacant seats and the number of vacant seats that account for 10% is smaller(1.6 and 2.5respectively). Therefore, the correct answer is: the 17:00 train.
2.At what hour does the most occupied train leave the station?
(most occupied train=the train with the greatest number of occupied seats)
A. 7:00 B. 8:00 C. 12:00 D. 17:00 E. 21:00 F. 7:00 and 21:00
答案解析:E
The most occupied train is the train with the greatest number of occupied seats,calculated as:
(Num. of seats) - (Num. of vacant seats).
Browsing the table quickly we are able to identify that the only train that will still have over 300
occupied seats after subtracting the number of vacant seats is the 21:00 train.
Therefore, the correct answeris 21 :00
3.If a person plans to travel from London to Barcelona via Amsterdam, leaving London by train at
12:00 pm GMT, with a one hour stop at Amsterdam, at what time would he arrive in Barcelona?
A. 18:00 GMT B. 19:00 GMT C. 20:00 GMT D. 21 :00 GMT E. 22:00 GMT F. 23:00
GMT
答案解析:E
The travel time from London to Amsterdam is 5. 5h. Taking into account a one hour lay off in
Amsterdam we can conclude that the total travel time from London to Amsterdam is: 5.5+1= 6.5
hours.
The travel time from Amsterdam to Barcelona is: 3.5 hours.
Therefore, the total travel time for this joumey is: 6.5+3.5= 10 hours.
So, if a person left London at 12:00 GMT, he will arrive in Barcelona at 22:00 GMT.
4.How much is the cost of the coffee maker offered by seller 1 more or less than the cost of the
coffee maker offered by seller 4 (both including a standard delivery fee)?
A. 26 less B. 26 more C. 16 less D. 16 more E. 14 less F. 14 more
答案解析:C
Seller 1 offers a price of 58 for the coffee maker and 20 delivery fee to arrive at a total of: 78.Seller 4 offers a price of E84 for the coffee maker and E10 delivery fee to arrive at a total of: 94.
The difference in prices between them is: 94-78= 16 ( less)
5.If you "buy it now", which seller offers the cheapest price (delivery not included)?(简答题)
答案解析:Instead of calculating the "buy it now" price for each seller, we can glance quickly at
the data to realize that seller 3 and 5 offer the highest discount. This, by itself, is not enough
information to make a solid conclusion. However, we may also notice that seller 5 and seller 6
offer the lowest original price on the coffee maker machine.
These two pieces of information help us eliminate 50% of the options with a high degree of
certainty, leaving us to calculate only 3 discount prices (seller 3,5 and 6):
SELLER 3: 140 with a 32% discount= 95.2
SELLER 5: 73 with a 21% discount= 57.67
SELL ER 6: 69 with a 14% discount= 59.34
It seems as though seller 5 offers the lowest price. Although we haven't checked all the prices,
we can conclude this with confidence.
6.What is the average standard delivery fair (excluding the 24h delivery fair) across
sellers?
A. 12.20 B. 18.66 C. 15.06 D. 10.16 E. 22.39 F. 7.69
答案解析:D
In order to calculate the average standard delivery fair we need to sum up all delivery costs
across sellers, and then divide the result by the number of seller (6):
(20+12+0+10+14+5)/6= 10.16
7.If I register for Zone 1 rates, how much money will I save on the special monthly offer?

12.What is the department with the highest number of overseas students?
A. History B. Arts C. Philosophy D. Physics E. Engineering F. Finance
答案解析:F
In this question we need to identify two important pieces of data:
(a) identify the most popular departments overall, and- (b) identify the departments with the
highest percentage of overseas students.
The most popular departments are (by far): Finance (730) and engineering (650).
The departments with the highest percentage of foreign students are: Physics (25%) and Finance

Now that we are narrowed our search to three options, we can calculate the number of foreign
students amongst these departments only:
Finance: 730* 0.2=146
Engineering: 650* 0.12=78
Physics: 348*0.25= 87
Thus, the correct answer is: Finance.
