Question

A trader makes a loss of 10% when he sells a watch for 15,300
what did it cost?​

Answer 1

CP = 17000

Explanation:

Given that,

Loss = 10%

Selling price of the watch, SP = $15,300

We need to find the cost price of the watch.

`CP=(100)/(100-L\%)* SP\\\\CP=(100)/(100-10)* 15300\\\\CP=17000`

So, the cost price of the watch is 17000.
