Question

By selling a jacket for Rs 729, Sunanda lost 10 %. What was the cost price of the
jacket?

Answer 1

810

Explanation:

SP = 729, LOSS = 10.1

`loss \: = ((cp - sp))/(cp) * 100 \\ \\ 10 = ( (cp - 729)/(cp) ) * 100`

10 CP = CP x 100 - 729 x 100

729 x 100 = 90 CP

`cp = (729 * 100)/(90) = 810`

Cost Price,

$810
