Based on the following data, calculate the percentage increase in total export earnings of India from 1935-36 to 1945-46. In 1935-36, total export earnings were Rs. 110 crores. In 1945-46, they rose to Rs. 165 crores.
Answer
50%
The correct answer is 50% — Thus the export earnings increased by 50% over the period.
Step-by-step solution
- Note the export earnings for the two years: Rs. 110 crores (1935-36) and Rs. 165 crores (1945-46).
- Find the absolute increase: 165 crores − 110 crores = 55 crores.
- Divide the increase by the initial value (110 crores) and multiply by 100 to get the percent change: (55/110) × 100 = 0.5 × 100 = 50%.
- Thus the export earnings increased by 50% over the period.
Common mistake: Using the final value as the denominator instead of the initial value
Concept tested: Growth in export earnings
