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. 1170 as rent for parking his cars, what is the total rent paid by all the four agencies?  Choose one
A) 2388 B) 2778 C) 1279 D) 6150 E) 6396
The ratio in which the four agencies will be paying the rents = 15 * 12 : 12 * 20 : 18 * 18 : 16 * 15   = 180 : 240 : 324 : 240 = 45 : 60 : 81 : 60   Let us consider the four amounts to be 45k, 60k, 81k and 60k respectively.   The total rent paid by the four agencies = 45k + 60k + 81k + 60k= 246k   It is given that A paid Rs. 1170   45k 45  + 60  + 81  + 60=

246k   It is given that A paid Rs. 1170   45k= 1170 =&gt; k = 26   246k = 246(26) = Rs. 6396   Thus the total rent paid by all the four agencies is Rs. 6396.   Answer: 6396
