Answer 1

Hey Dear,

◆ Answer -

A's contribution = 104 Rs

B's contribution = 128 Rs

C's contribution = 168 Rs

◆ Explaination -

A's 13 cows grazed for 6 months -

A = 13 × 6 = 78 cow months

B's 12 cows grazed for 8 months -

B = 12 × 8 = 96 cow months

C's 14 cows grazed for 9 months -

C = 14 × 9 = 126 cow months

Contribution of each will depend upon how much they grazed their cows.

A's contribution is given as -

A's contribution = 400 × 78 / (78 + 96 + 126)

A's contribution = 104 Rs

B's contribution is given as -

B's contribution = 400 × 96 / (78 + 96 + 126)

B's contribution = 128 Rs

C's contribution is given as -

C's contribution = 400 × 126 / (78 + 96 + 126)

C's contribution = 168 Rs

Hope this helps you...
