Practicing Success
A and B rent a pasture for 12 months and A puts in 70 cows for 9 months. How many cows can B put in for the remaining 3 months, if he pays half as much as A? |
75 115 90 105 |
105 |
Let the rent for one cow = Rs.1/pm Then, rent for each partners = no. of cows × time A : B No. : 70 : x Time : 9 : 3 ------------------------- Rent : 630 : 3x So ATQ, B paid half the rent paid by A = \(\frac{630}{2}\) = 315 ⇒ 3x = 315 ⇒ x = 105 Therefore, B puts in 105 cows for the rest 3 months. |
