# Quantitative Aptitude: Data Interpretation Questions Set – Set 88

Directions(1-5): Study the following line graph carefully in which x-axis represents the year and the y-axis represents the number of students(in hundreds) in three specific colleges A , B and C.

1. What was the average number of students in college C ?
1000
4500
2000
3000
2200
Option C
Required Numbers = (1000+500+2000+1500+2000+5000)/6
= 12000/6 = 2000

2. What was the ratio between the total number of students in college B in the year 2005 and 2007 together and in college A in the year 2006 and 2010 ?
4:9
7:12
11:13
5:17
10:19
Option B
Ratio = (2000+1500) : (1500+4500) =35:60 = 7:12

3. What was the average number of students in school B in the year 2006, 2008 and 2010?
4000
5000
6000
2000
3000
Option E
Required average numbers of students = 9000/3
= 3000

4. What was the difference between the total number of students in the year 2007 and 2009 in all the three colleges ?
3500
1250
1560
4500
1000
Option A
Total number of students from all the three colleges in the year 2007
= (2000+2000+1500) = 5500
Total number of students from all the three colleges in the year 2009 = (2000+3000+5000) = 9000
Required difference = 9000 â€“ 5500 = 3500

5. Total number of students in the college C in the year 2005 and 2009 was approximately what percentage of the total number of students in college A in the year 2008 and 2010 ?
43%
20%
40%
50%
33%
Option A
Number of students in college C in the year 2005 and 2009 = (2000+1000) = 3000
Number of students in college A in the year 2008 and 2010 = (2500 + 4500 ) = 7000
Percentage = ( 3000*100)/7000 = 43%(approx.)

Directions(6-10): Study the table carefully and answer the following questions.

1. What is the cost of flooring and cost of fencing of parallelogram?
Rs.10550 and Rs.800
Rs.950 and Rs.500
Rs.10,500 and Rs.1400
Rs.11,500 and Rs.600
Rs.12,200 and Rs.650
Option C
Area of parallelogram = (20*15) = 300 sq. m
Cost of flooring = 300 * 35 = Rs. 10,500
Perimeter of parallelogram = 2(20+15) = 70 m
Cost of fencing = 70*20 = Rs.1400

2. What is the ratio of the area between circle and triangle ?
77:24
61:30
70:53
55:37
None of these
Option A
Area of circle = pi*r*r = 154 sq.m
Area of triangle = Â½*8*12 = 48 sq. m
Ratio = 154:48 = 77 : 24

3. What is the cost of flooring rectangle ?
Rs.5,460
Rs.6,650
Rs.4,230
Rs.4,440
Rs.6,656
Option E
Area of rectangle = 208 sq.m
Cost of flooring = 208 * 32 = Rs.6,656

4. Find the difference between the cost of fencing of circle and cost of flooring of square?
Rs.52,250
Rs.61,490
Rs.78,680
Rs.63,550
Rs.42,000
Option C
Difference = cost of flooring of square – cost of fencing of circle
Required difference = (40*40*50)- (44*30) = 80,000 – 1320
= Rs.78,680

5. By what percent the area of rectangle is more or less than the area of parallelogram?
22.25%
30.67%
20.12%
15.6%
33.33%
Option B
Required % = (300-208)*100/300 = 30.67%
