Question

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

Answer 1

Answer:

810

Step-by-step explanation:

SP = 729, LOSS = 10.1

$loss \: = \frac{(cp - sp)}{cp} \times 100 \\ \\ 10 = ( \frac{cp - 729}{cp} ) \times 100$

10 CP = CP x 100 - 729 x 100

729 x 100 = 90 CP

$cp = \frac{729 \times 100}{90} = 810$

Cost Price,

$810
