this chart represents the imports and exports of pakistan during the period 1982-1988 in billions of pakistani rupees (rs). the darker bars represent imports, and the lighter bars are exports.

1. in which year did the value of exports exceed the value of imports by the greatest amount?

(a) 1982-1983
(b) 1983-1984
(c) 1984-1985
(d) 1987-1988

1. what was the average approximate value of the exports in (rs) for the six years shown in the chart?

(a) 48 billions
(b) 62 billions
(c) 75 billions
(d) 88 billions
30.. what was the average annual increase for imports in (rs) for the six years shown in the chart?
(a) 7 billions
(b) 8.4 billions
(c) 11 billions
(d) 42 billions

Explanation:

28.

Step1: Calculate export - import for each year

For 1982 - 1983: \(65 - 30=35\)
For 1983 - 1984: \(75 - 35 = 40\)
For 1984 - 1985: \(90 - 40=50\)
For 1987 - 1988: \(110 - 80 = 30\)

Step1: Sum of exports

\(65+75 + 90+90+95+110=525\)

Step2: Calculate average

Average \(=\frac{525}{6}=87.5\approx88\)

Step1: Find initial and final import values

Initial import (1982 - 1983): \(30\)
Final import (1987 - 1988): \(80\)

Step2: Calculate increase

Increase \(=80 - 30=50\)

Step3: Calculate average annual increase

Average annual increase \(=\frac{50}{5}=10\approx11\)

Answer:

C. 1984 - 1985
