Four milkmen rented a pasture. A grazed 24 cows for 3 months; B 10 for 5 months; C 35 cows for 4 months and D 21 cows for 3 months. If A's share of rent is Rs. 7200, find the total rent of the field.
Select the correct option:  A) 37500  B) 35500  C) 42500  D) 22500  E) 32500
Ratio of shares of A, B, C, D = (24 x 3) : (10 x 5) : (35 x 4) : (21 x 3) = 72 : 50 : 140 : 63.   Let total rent be Rs. x. Then, A’s share = Rs. (72x)/325   (72x)/325=7200 = x=(7200 x 325)/72 = 32500   Hence, total rent of the field is Rs. 32500.   Answer is 32500.
