Question

The price of one litre of petrol is Rs 42.40. A man paid Rs 100 for 2.5 litre of petrol for his bike. Is it more than the required amount or less? By how much?

Answer 1

Price of 1 litre of petrol = Rs 42.40

Money paid for 2.5 litres of petrol = Rs 100

Total cost of petrol = Price of 1 litre of petrol × Total litres of petrol bought

= Rs 42.40 × 2.5

= Rs

= Rs

= Rs

= Rs 106

The amount paid by the man is less than the required amount.

Required difference = Rs 106 − Rs 100 = Rs 6

Thus, the man paid Rs 6 less than the required amount.
