Question 9. 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?

Answer :

The ratio in which the four groups could be paying the rents = 15 * 12 : 12 * 20 : 18 * 18 : 16 * 15

= a hundred and eighty : 240 : 324 : 240 = forty five : 60 : eighty one : 60

Let us consider the 4 amounts to be 45k, 60k, 81k and 60k respectively.

The general hire paid by means of the 4 corporations = 45k + 60k + 81k + 60k= 246k

It is for the reason that A paid Rs. 1125

45k = 1125 => okay = 25

246k = 246(25) = Rs. 6150

Thus the total lease paid by all the four businesses is Rs. 6150.
