Question

Find the C.P when S.P = ₹360; Loss = 10%

Answer 1

Answer : $\bold{Cost \: Price \: = \: Rs \: 400}$



Explanation -


Given :

Selling Price = ₹ 360

Loss = 10 %


Finding Cost Price -


$cost \: price \: = \dfrac{100}{100 - loss} \times sp$



$cost \: price \: = \dfrac{100}{100 - 10} \times 360$



$cost \: price \: = \dfrac{100}{90} \times 360$


$cost \: price \: = \dfrac{36000}{90}$



$cost \: price \: = 400$



Hence :

$\bold{Cost \: Price \: = \: Rs \: 400}$

Answer 2

Answer : \bold{Cost \: Price \: = \: Rs \: 400}CostPrice=Rs400
