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:

C. ₹832

Read Explanation:

Distance travelled per month = 3045 km

Mileage = 15 km/litre

Petrol required per month:

304515=203\frac{3045}{15}=203

So, petrol consumed = 203 litres.

Increase in petrol price:

5% of 82=5100×82=4.15\% \text{ of } 82 = \frac{5}{100}\times82 = 4.1

Increase in monthly expenditure:

203×4.1=832.3203\times4.1=832.3

To the nearest rupee, the increase is ₹832.
