Four car rental agencies A, B, C and D rented a plot for parking their cars during the night. A parked 15 cars for 12 days, B parked 12 cars for 20 days, C parked 18 cars for 18 days and D parked 16 cars for 15 days. If A paid Rs. 1125 as rent for parking his cars, what is the total rent paid by all the four agencies?
Correct answer: D. Rs. 6150
- A. Rs. 4500
- B. Rs. 4800
- C. Rs. 5250
- D. Rs. 6150
- E. None of these
Explanation
Rent is proportional to the number of cars multiplied by the number of days. A used 15 x 12 = 180 car-days, so the rate was Rs. 1125/180 = Rs. 6.25 per car-day; the total is (180 + 240 + 324 + 240) x Rs. 6.25 = 984 x Rs. 6.25 = Rs. 6150. Option a is a likely choice if the agencies' different parking durations are overlooked.
