Answer & Explanation
Bar Diagram 52
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
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
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
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
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
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.
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
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.
S4. Ans.(c)
Sol. Clearly, by visual inspection D is the desired option.
S5. Ans.(c)
Sol. Percentage production of B type cars in 1997 = that in 1996 (given)
= (40 – 15) 25% of 520000 = 130000.
