7.Profit and Loss
medium
A man buys a table and a chair for $Rs.\, 500.$ He sells the table at a loss of $10 \%$ and the chair at a gain of $10 \% .$ He still gains $Rs.\, 10$ on the whole. The cost price of chair in rupees is
A
$200$
B
$250$
C
$300$
D
$350$
Solution
Let the price of Table be $T$
Let the price chair be $C$
$T + C =500$ … $(I)$
$C \times 10 \%- T \times 10 \%=10$
$C \times \frac{1}{10}-T \times \frac{1}{10}=10$
$C-T=100$ $…(II)$
Solving $(I)$ and $(II)$ we get $C=300$ and $T=200$
