Question

Value of exports of raw materials during 1984–85 was how much percent less than that for 1985–86?

• A. 39
• B. 46.18
• C. 7
• D. 31.6

Hint:

Always subtract earlier year from later year before dividing by the later year’s value when finding “percent less.”

Answer 1

The Correct Option is D

Step 1: 1985–86 raw material value
Given: In 1985–86, ratio of raw material to manufactured articles = 3:4.
Let raw = \( 3x \), manuf = \( 4x \).
Food in 1985–86 = Rs. 5934 crore.
Total = \( 3x + 4x + 5934 = 25800 \)
\( 7x = 25800 - 5934 = 19866 \).
\( x = 2838 \) crore.
Thus, raw = \( 3x = 8514 \) crore.
Step 2: 1984–85 raw material value
From Q161: R = 5824 crore.
Step 3: Calculate percentage less
Difference = \( 8514 - 5824 = 2690 \) crore.
Percent less = \( \frac{2690}{8514} \times 100 \approx 31.6% \).
Step 4: Cross-check
If 31.6% of 8514 = 2690, then 8514 - 2690 = 5824, which matches 1984–85 raw.
Thus, the answer is (d) 31.6%.
