-
- ₹ 8550
- ₹ 5950
- ₹ 9200
- ₹ 6750
Correct Option: A
Floppy - days = Number of floppies X Days run
Here, A's floppy - days : B 's floppy - days : C's floppy - days = A's payment for rent : B 's payment for rent : C's payment for rent
= 27 x 19 : 21 x 17 : 24 x 23
A's rent : B's rent : C's rent = 171 : 119 : 184
∴ Payment for rent by A = [171/(171 + 119 + 184)] x 23700 = ₹ 8550
