Question

A man buys a $T.V$ for how much should he sell it so to
(i) gain $10\%$
(ii) less $5\%$ on it?

Answer 1

Let cost price of $T.V$ be $Rs.100$

Profit $=\frac{10}{100}\times 100=Rs.10$

$\therefore$ Selling price must be $=Rs.110----Ans\left(i\right)$

Loss $=\frac{5}{100}\times 100=Rs.5$

$\therefore$ Sellinf price must be $=Rs.95---Ans\left(ii\right)$
