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 ?
Answer & explanation
Correct answer: option 3
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
