Correct Answer: 20%
Solution : Given: Let us assume the cost of the petrol before increasing is Rs 100. The petrol price has increased by 25 %. The increased price will be – ⇒100 + (25 ÷ 100) × 100 ⇒100 + 0.25 × 100 ⇒100 + 25 ⇒125 Rs The increased expenditure = 125 – 100 = 25 Rs So, consumption of petrol should decrease by percentage = (25 ÷ 125) × 100 ⇒0.20 × 100 = 20%
So, Yogesh should decrease his travel expenses by 20%. Hence, the fourth option is correct.
