Four milkmen A, B, C and D hired a pasture. A had 9 cows that graze for 5 months, B had 12 cows that graze for 3 months, C had 16 cows that graze for 2 months and D had 10 cows that graze for 4 months. If A paid Rs.225 then what was the rent of the pasture?
Answer & explanation
Correct answer: option 2
Let the rent for one cow = Rs.1/pm
Then, rent for each partners = no. of cows × time
A : B : C : D
No. : 9 : 12 : 16 : 10
Time : 5 : 3 : 2 : 4
----------------------------------------------------
Rent - 45 : 36 : 32 : 40 = 153
So rent paid by A = 45R = 225
1R = 5
Total Rent = 153R = 153 × 5 = Rs.765
