Q:

Three milkmen rented a pasture. A grazed 24 cows for 4 months; B 10 cows for 6 months; C 56 cows for 5 months. If A's share of rent is Rs. 960, find the total rent of the field?

A) 4530 B) 4440
C) 4360 D) 4280
 
Answer & Explanation Answer: C) 4360

Explanation:

Ratio of shares of A,B,C = (24 x 4) : (10 x 6) : (56 x 5)

                                    = 96 : 60 : 280.

 

Let total rent be Rs. x. Then, A's share = Rs.96x436

 96x436=960 x=960×43696=4360

 

Hence total rent of the field is Rs. 4360.
