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. 720, find the total rent of the field.
Choose the correct choice from the following answers:
A) 3750
B) 3550
C) 4250
D) 2250
E) 3250
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=720 = x=(720 x 325)/72 = 3250   Hence, total rent of the field is Rs. 3250.   Answer is 3250.
