Question

Find the gain or loss percent in the following case$:$

$C.P.$ $₹100$ and $S.P.$$₹90$

Answer 1

Step $1:$ To find the loss or gain .

It is given that $C.P.$ $=$$₹100$

and $S.P.$ $=$ $₹90$

$C.P.>S.P.$ there will be a loss

$Loss$ $=$$C.P.-S.P.$

$Loss=100-90$

$Loss=₹10$

Step $2:$ Now find the loss percent.

Loss percent $=\frac{C.P.-S.P}{C.P}\times 100$

loss percent $=\frac{Loss}{C.P.}\times 100$

$=\frac{10}{100}\times 100$ $,$ cancel $100$ by $100$

$=10\%$

Hence, the loss percent is $10\%$
