Question

A man buys a transistor for $₹250$ and sells it gaining $₹25$ Find his gain percent$.$

Answer 1

Step $1:$ To find gain percent on a transistor.

It is given that $C.P.$ of transistor $=$$₹250$

Gain $=$$₹25$

Step $2:$ Now find gain percent using formula.

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

$=\frac{25}{250}\times 100$ $,$ Cancel $25$ from numerator and denominator

$=\frac{1}{10}\times 100$ $,$ Cancel $100$ by $10$

$=10\%$

Hence, the gain percent is $10\%$ .
