# Quantitative Aptitude: Data Interpretation Set 4

Directions (1 – 5): A survey is taken in 6 cities of a state. The pie chart shows the distribution of people in each city with total 8,40,000 people. 1. Number of people in city B is how much percent greater than the number of people in city D?
A) 8%
B) 50%
C) 15%
D) 35%
E) 42%
Option B
Solution:

A = 117600, B = 201600, C = 109200, D= 134400, E = 100800, F = 176400
So here – [(201600-134400)/134400] × 100 = 50%
2. What is the total number of people in cities C, E and F?
A) 3,86,400
B) 3,45,670
C) 3,24,500
D) 3,67,400
E) 3,66,400
Option A
Solution:

A = 117600, B = 201600, C = 109200, D= 134400, E = 100800, F = 176400
3. What is the ratio between number of people in cities F and C together and that in B and E together?
A) 16 : 17
B) 15 : 22
C) 17 : 20
D) 17 : 18
E) 18 : 23
Option D
Solution:

A = 117600, B = 201600, C = 109200, D = 134400, E = 100800, F = 176400
176400 + 109200 : 201600 + 100800
2856 : 3024
17 : 18
4. If there are 65% males in city B, 49% females in city D and 47% males in city E, then females in these cities form what percent of total number of people in these three cities?
A) 52.33%
B) 45.37%
C) 32.56%
D) 44.08%
E) None of these
Option D
Solution:

A = 117600, B = 201600, C = 109200, D = 134400, E = 100800, F = 176400
Females in B, D, and A = 35/100 × 201600 + 51/100 × 134400 + 53/100 × 100800 = 192528
So % = [192528/(201600+134400+100800)] × 100 = 44.08%
5. Number of people in city A is what percent of the number of people in city C?
A) 111.91%
B) 123.25%
C) 107.69%
D) 119.31%
E) 126.22%
Option C
Solution:

14/13 × 100

Directions (6- 10): Study the following carefully and answer the questions that follow:
The bar graph shows the number of sales of Televisions (in Thousands) each year by three companies in 3 consecutive years. The line chart shows the average price per television (in Thousands Rupees) for these three consecutive years. 1. How much money (in million) did Toshiba make for the year 2013?
A) 19800
B) 18260
C) 12700
D) 15640
E) 12330
Option D
Solution:

In 2013, Toshiba sold = 460 thousand
Average price in 2013 is Rs 34
So total money is (34 × 460) million
2. What is the average number of Televisions sold per year over the given three years?
A) 1680
B) 1430
C) 1560
D) 1400
E) 1510
Option E
Solution:

Sold in 2012 = 560+440+450 = 1450
Sold in 2013 = 510+460+490 = 1460
Sold in 2014 = 590+480+550 = 1620
Total number sold in 3 years = 1450+1460+1620 = 4530
So average = 4530/3 = 1510
3. What percent of total money generated by selling Televisions from Toshiba in 2014?
A) 61%
B) 64%
C) 52%
D) 78%
E) 56%
Option B
Solution:

Total money generated in 2014 by selling all = 590*10 + 480*33 + 550*5 = 24490 million
Total money generated in 2014 by selling Toshiba only = 480*33 = 15840 million
So % = [15840/24490] × 100 = 64%
4. What is the percent change in the average price of television in the year 2013 compared to the year 2012?
A) 1.9% increased
B) 2.9% decreased
C) 1.9% decreased
D) 2% increased
E) 3.0% decreased
Option C
Solution:

Avg price in 2012 = (10+35+7)/3 = 17.33
Avg price in 2013 = (11+34+6)/3 = 17
So % change = [(17.33-17)/17.33] × 100 = 1.9% decreased
5. If in 2015, Sony wants to decrease the average price of its each Television by 10% then how many Televisions they have to sell (in thousands) so that the amount of money generated by selling Televisions remains unchanged compared to the previous year?
