Question

"0. A man loses 10% by selling his watch for
450. Find the cost price of the watch.​

Answer 1

Answer:

HEY MATE!!! HOPE YOU FIND THIS HELPFUL.

Step-by-step explanation:

CP = SP + LOSS

CP = 450 + ($\frac{10}{100}$ × CP)

CP = 450 + $\frac{CP}{10}$

CP - $\frac{CP}{10}$ = 450

$\frac{10CP - CP}{10}$ = 450

$\frac{9CP}{10}$ = 450

CP = $\frac{450 * 10}{9}$

CP = 500

Cost price of watch is Rs. 500
