Correct answer: A
Concept: In an export–import data set, the income of a group of countries for a given year is what their exports earn less what their imports cost — Income = Total exports − Total imports. Only the column belonging to that one year enters the calculation; figures from the other years play no part.
Application — build the 2023 export total from the table, then subtract the imports given in the question:
Read the 2023 exports of each country from the table: A = 180, B = 200, C = 130, D = 50, E = 220 and F = 240, all in ₹ crore.
Add them in convenient pairs: (180 + 200) + (130 + 50) + (220 + 240) = 380 + 180 + 460.
380 + 180 + 460 = 1020, so the six countries together exported ₹ 1020 crore in 2023.
Apply the relation with the imports stated in the question: Income = 1020 − 770 = 250.
Result: taken together, the six countries had an income of ₹ 250 crore in 2023.
Cross-check: adding the imports back must return the export total — 250 + 770 = 1020, which is exactly the 2023 column sum, so the subtraction is consistent. Watch the year too: the 2021 column adds to ₹ 560 crore and the 2020 column to ₹ 540 crore, so totalling the wrong column changes the result even when the method is right.
