Question

the watch is sold at rs 400 at loss . if it had been sold rs 500 the profit would have been 2/3 of origin loss, the cost price of the watch is ?​

Answer 1

Explanation:

Let the cost price of the watch=x Rs.

*loss=(x-400)rs

*profit=(500-x)rs

Now according to the problem

500-x=(2/3)(x-400)

1500-3x=2x-800

2300=5x

x=2300/5=460rs

Therefore the cost price is 460 Rs
