Show answer & explanation
Correct answer: D
Concept
For successive values, the percentage increase is measured relative to the earlier value, not merely by the absolute increase.
If a quantity changes from P to N, percentage increase = ((N - P) / P) × 100. The same formula must be applied to every adjacent pair before comparing the rates.
Application
Apply the formula to the Net National Income column for each year after 2015-16:
2016-17: ((136 - 122) / 122) × 100 = (14 / 122) × 100 ≈ 11.48%.
2017-18: ((151 - 136) / 136) × 100 = (15 / 136) × 100 ≈ 11.03%.
2018-19: ((167 - 151) / 151) × 100 = (16 / 151) × 100 ≈ 10.60%.
2019-20: ((177 - 167) / 167) × 100 = (10 / 167) × 100 ≈ 5.99%.
Cross-check
For an exact comparison, 14/122 exceeds 15/136 because 14 × 136 = 1904 > 15 × 122 = 1830; it also exceeds 16/151 and 10/167 by the same cross-multiplication check.
Result
Therefore, the maximum percentage increase occurred in 2016-17, at approximately 11.48%.
