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. 1260 as rent for parking his cars, what is the total rent paid by all the four agencies?  Answers:
A) Rs. 4500
B) Rs. 4800
C) Rs. 5250
D) Rs. 6888
E) None of these
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. 1260   45k 45  + 60  + 81  + 60=

246k   It is given that A paid Rs. 1260   45k= 1260 =&gt; k = 28   246k = 246(28) = Rs. 6888   Thus the total rent paid by all the four agencies is Rs. 6888.   ANSWER:Rs. 6888
