A merchant bought 60 sheep at Rs. 120 per sheep. He sold 40 of them at Rs.150. 10 of the sheep died. If he wants to profit of Rs. 800, the selling price is

The cost of each sheep$=$ Rs. 120

The cost of 40 sheeps$=40\times 120=7200$

In that sheep sold Rs.150 for each sheep

$40\times 150=$ Rs.6000

In that 10. Of the sheeps died

Merchant has 10 sheeps.

$\therefore$  the selling price of each goat in $\frac{2000}{10}$

$=$ Rs.200
