The petrol prices shot up by 7% as a result of the hike in the price of crudes. The price of petrol before the hike was ₹28 per litre. Vawal travels 2400 kilometres every month and his car gives a mileage of 18 kilometres to a litre. Find the increase in the expenditure that Vawal has to incur due to the increase in the price of petrol (to the nearest rupee)?
Answer and explanation
Correct answer B
The correct choice is: “₹261”
Petrol used per month = 2400 ÷ 18 = 133⅓ litres.
Increase in price per litre = 7% of ₹28 = ₹1.96.
Increase in monthly expenditure = 133⅓ × 1.96 = ₹261.33 (check: 133⅓ × 29.96 − 133⅓ × 28 = 3994.67 − 3733.33 = 261.33).
To the nearest rupee this is ₹261. “₹270”, “₹272” and “₹276” are all ₹9 or more away from the true increase.
