Question

Mr. Tandon purchased a computer for Rs. $32000$ and a microwave oven for Rs. $6500$. On computer he lost $5$% and on microwave he gained $15$%. Find his total gain or loss per cent

• A. Gain $=7\%$
• B. Gain $=6\%$
• C. Loss $=7\%$
• D. Loss $=6\%$

Answer 1

The correct option is A Gain $=7\%$

Let the original prices be $p,q$;

$p=\frac{32000\times 20}{19};q=\frac{6500\times 20}{17}$

$\frac{p+q-38500}{p+q}\times 100=7$%.

A gain of $7$%
