Question

A man buys a T.V for Rs.6800. For how much should he sell it so as to
i) gain 10%
ii) lose 5% on it?

Answer 1

We know that,

Cost price of $T.V=6800$

(i) Selling price of $T.V$ so as to gain $10$% on it

$=6800+6800\times \frac{10}{100}$

$=6800+680$

$=7480$

(ii) Selling price of $T.V$ so as to loss $5$% on it

$=6800-6800\times \frac{5}{100}$

$=6800-340$

$=6460$
