Two persons A and B take a field on rent. A puts on it 21 horses for 3 months and 15 cows for 2 months; B puts 15 cows for 6months and 40 sheep for 7 1/2 months. If one day, 3 horses eat as much as 5 cows and 6 cows as much as 10 sheep, what part of the rent should A pay?

A. 1/3 rd
B. 2/5 th
C. 2/3 rd
D. 1/5 th

Explanation:

3h = 5c

6c = 10s

A = 21h*3 + 15c*2

= 63h + 30c

= 105c + 30c = 135c

B = 15c*6 + 40s*7 1/2

= 90c + 300s

= 90c + 180c = 270c

A:B = 135:270

27:52

A = 27/79 = 1/3

Correct Answer: 1/3 rd ✔
