| Four transport companies A, B, C and 9 rented a parking place. A kept 12 cars for 5 months, B kept 20 cars for 6 months, C kept 15 cars for 5 months and D kept 30 cars for 6 months in the parking place. If A's share of rent is Rs. 2400, then the total rent of the parking place is |
A) Rs. 17400
B) Rs. 18600
C) Rs. 16500
D) Rs. 19200
Correct Answer: A
Solution :
| Ratio of shares of A, B, C and D |
| \[=(12\times 5):(20\times 6):(15\times 5):(30\times 6)\] |
| \[=60:120:75:180=4:8:5:12\] |
| Let the total rent for the parking place be Rs. x. |
| As, share \[=\frac{4x}{29}\] |
| \[\therefore \]\[\frac{4x}{29}=2400\]\[\Rightarrow \]\[x=\frac{2400\times 29}{4}=17400\] |
