Concept

In table-based Data Interpretation, when a question asks for the year with the least (or greatest) difference between two given quantities, compute the absolute difference between those two quantities for the year in each row, then compare the resulting differences to find the smallest (or largest) one.

Application

1. 2007: Social Science High marks = 65, Average marks = 55, so the difference = 65 − 55 = 10.

2. 2008: Social Science High marks = 66, Average marks = 58, so the difference = 66 − 58 = 8.

3. 2009: Social Science High marks = 68, Average marks = 48, so the difference = 68 − 48 = 20.

4. 2010: Social Science High marks = 77, Average marks = 58, so the difference = 77 − 58 = 19.

Cross-check

Comparing all four differences — 10, 8, 20, and 19 — the smallest value is 8, which belongs to 2008. Re-checking that row independently (66 − 58 = 8) confirms no other year produces a smaller gap.

Result

The difference between the Highest and Average marks in Social Science is least in 2008.
