Question

The price of petrol shot up by 5%. Before the hike, the price was Rs. 82 per litre. A man travels 3045 km every month and his car gives a mileage of 15 km per litre. What is the increase in the monthly expenditure (to the nearest Rs.) on the man's travel due to the hike in the petrol prices?

• A. ₹850
• B. ₹820
• C. ₹832
• D. ₹845

Answer 1

Answer:

C. ₹832

Distance travelled per month = 3045 km

Mileage = 15 km/litre

Petrol required per month:

$\frac{3045}{15}=203$

So, petrol consumed = 203 litres.

Increase in petrol price:

$5\% \text{ of } 82 = \frac{5}{100}\times82 = 4.1$

Increase in monthly expenditure:

$203\times4.1=832.3$

To the nearest rupee, the increase is ₹832.
