Four milkmen rented a pasture. A grazed 18 cows for 4 months, B grazed 25 cows for 2 months, C grazed 28 cows for 5 months and D grazed 21 cows for 3 months. If A's share of rent is ₹ 720, what will be the total rent of the pasture ?
-
- ₹ 1650
- ₹ 3250
- ₹ 3500
- ₹ 3000
Correct Option: B
Ratio of rents of A, B, C and D
= (18 x 4) : (25 x 2) : (28 x 5) : (21 x 3)
= 72 : 50 : 140 : 63
Let the total rent be N.
Then, A's share = [72N / (72 + 50 + 140 + 63)] = 72N/325
According to the question. 72N/325 = 720
∴ N = (720 x 325)/72 = 3250
∴ Total Rent = ͭ 3250
