Data Interpretation


Directions (1-5): Study the following graph carefully and then answer the questions based on it. The percentage of five different types of cars produced by a company during two years is given below.


Total Production of Cars in 1996 was 450000
Total Production of Cars in 1997 was 520000

Q1. What was the difference in the production of C type cars between 1996 and 1997?
(a) 5000
(b) 7500
(c) 10000
(d) 2500
(e) None of these

S1. Ans.(a)
Sol. Production of C type cars in 1996
= (70 – 40)% of 450000
= 30% of 450000 = 135000
Production of C type cars in 1997
= (65 – 40)% of 520000
= 25% of 520000 = 130000
∴ Required difference = 5000.

Q2. If 85% of E type cars produced during 1996 and 1997 are being sold by the company, then how many E type cars are left unsold by the company?
(a) 142800
(b) 21825
(c) 29100
(d) 25200
(e) None of these

S2. Ans.(e)
Sol. Production of E type cars in 1996
= (100 – 80)% of 450000
= 20% of 450000 = 90000
And in 1997 = 10% of 520000 = 52000
∴ Total production = 90000 + 52000 = 142000.
∴ Required number of cars = 15% of 142000 = 21300

Q3. If the number of A type cars manufactured in 1997 was the same as that of 1996, what would have been its approximate percentage share in the total production of 1997?
(a) 11
(b) 13
(c) 15
(d) 9
(e) None of these

S3. Ans.(b)
Sol. Production of A type cars in 1997 = production of A type cars is 1996 (given) 
= (100 – 85)% of 450000 = 67500
∴ Required percentage = 67500/520000× 100 ≈ 13. 

Q4. In the case of which of the following types of cars was the percentage increase from 1996 to 1997 the maximum?
(a) A
(b) E
(c) D
(d) B
(e) C

S4. Ans.(c)
Sol. Clearly, by visual inspection D is the desired option.

Q5. If the percentage production of B type cars in 1997 was the same as that of 1996, what would have been the number of cars produced in 1997?
(a) 112500
(b) 120000
(c) 130000
(d) Data inadequate
(e) None of these

S5. Ans.(c)
Sol. Percentage production of B type cars in 1997 = that in 1996 (given)
= (40 – 15) 25% of 520000 = 130000.

Directions (6-10): The following bar graph depicts the result for BSc students of a college for the three years. Read the graph and answer the questions based on this graph.



Q6. The number of students passed in third division in 1984 was
(a) 165
(b) 75
(c) 70
(d) 65
(e) None of these

S6. Ans.(b)
Sol. Required number of students passed in third division 
= 170 – 95 = 75

Q7. The percentage of students failed in1984 was
(a) 18(1/2)%
(b) 17(3/4)%
(c) 15%
(d) 17%
(e) None of these

S7. Ans.(c)
Sol. Percentage of students failed in 1984
= 30/200× 100 = 15 %

Q8. The aggregate pass percentage during the three years was
(a) 82(44/113)%
(b) 82(55/113)%
(c) 82(26/107)%
(d) 77(29/113)%
(e) None of these


Q9. The percentage of students passed in first division in 1982 was
(a) 20%
(b) 34%
(c) 14(2/7)%
(d) 13(23/29)%
(e) None of these
Q10. The percentage of students passed in 1982 was
(a) 65%
(b) 70%
(c) 74(2/17)%
(d) 82 (22/29)%
(e) None of these
