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%
