Correct answer: C
Concept
A percentage increase compares the change with the original value, not with the new value. If the original total is O and the later total is N, then percentage increase = ((N - O) / O) × 100.
Application
Add the six exports for 2020: O = 80 + 50 + 110 + 120 + 100 + 80 = 540 crore rupees.
Add the six exports for 2022: N = 90 + 100 + 180 + 30 + 200 + 150 = 750 crore rupees.
Find the increase: N - O = 750 - 540 = 210 crore rupees.
Divide by the 2020 total and convert to a percentage: (210 / 540) × 100 = 38.888...%, which is approximately 38.89%.
Cross-check
Applying 38.89% to the 2020 total gives 540 × 1.3889 ≈ 750, which reproduces the 2022 total after rounding.
Result
Therefore, the approximate percentage increase is 38.89%.
