Level 2 – Line Graph Practice Quiz-3-Medium

DIRECTIONS for questions 1-5: Study the following graph carefully and answer the line graph problems given below:

1. The aggregate expenditure of which of the following sets of years was equivalent to the income in 1990?
A. 1987 & 1988

B. 1987 & 1989

C. 1988 & 1989

D. None of these

Answer & Explanation
Answer Option: D
Going by options: For 1987 & 1988, the total expenditure = 450 + 400 = 850 cr.
For 1987 & 1989 the total expenditure = 450 + 350 = 800 cr.
For 1988 & 1989 the total expenditure = 400 + 350 = 750 cr.
Income in 1990 = 400 cr. None of the options satisfies.

2. What was the approximate percentage decrease in income from 1987 to 1988?
A. 80%

Answer Option: D
For 1987, % of expenditure to Income = 450 / 300 = 1.5
For 1988, % of expenditure to Income = 400 / 250 = 1.6
For 1989, % of expenditure to Income = 350 / 200 = 1.75
For 1990, % of expenditure to Income = 450 / 400 = 1.125
Obviously it is lowest for 1990.
