Four milkmen A, B, C and D hired a pasture. A had 10 cows that graze for 2 months, B had 11 cows that graze for 3 months, C had 14 cows that graze for 4 months and D had 8 cows that graze for 5 months. If A paid Rs.560 then what was the rent of the pasture ?

4172

Let the rent for one cow = Rs.1/pm

Then, rent for each partners = no. of cows × time

            A   :   B     :   C     :   D

No.   :  10   :  11   :  14     :  8

Time :   2   :   3   :   4     :   5  

----------------------------------------------------

 Rent -  20  :  33  : 56    :   40   = 149

So rent paid by A = 20R = 560

1R = 28

Total Rent = 149R = 149 × 28 = Rs.4172
