Best answer
Correct Answer - Option 3 : 12

Given

The index number for the price of diesel in 2015 was 125 and in 2016, it was 140, on a base year of 2011

Formula

% change = [(Final - initial)/initial] × 100

Calculation

% change = (140 - 125)/125] × 100

⇒ [15/125] × 100

∴ The percent increase in price of diesel from 2015 to 2016 is 12%
