Question : 13 of 150

Marks: +1, -0

A and B rent a pasture for 10 months; A puts in 80 cows for 7 months. How many can B put in for the remaining 3 months, if he pays half as much again as A?

Validate

Solution:

Let B puts = x cows
then amount paid by B =

3/2

× amount paid by A.
∴

{80×7}/{x×3}

{\amount \paid \by \B}/{3/2 × \amount \paid \by \A}

⇒ x =

{80×7×3}/{3×2}

= 280 cows
