A taxi driver makes a profit of 20% on every trip when he carries 3 passengers and the price of petrol is Rs. 60 a litre. Find the percent profit for the same journey if he goes for 4 passengers per trip and the price of petrol reduces to Rs. 48 litres?
Answer with explanationAnswer: Option A
When 3 passengers income was 3x
profit =20% of 60 = Rs.12
that means his earning is Rs.72, so that per passenger fare must be Rs.24
When 4 passengers
earning = 24×4=Rs.96
profit = Rs.48 = 100%
