Question

ON selling a bed for Rs, 10800, a Carpenter loses 10%. For that amount should he sell it to gain 5%?

Answer 1

If S.P$=10,800$

Loss is $10\%$

$\Rightarrow 10,800$ is $90\%$ of C.P

$\Rightarrow \frac{90}{100}\times C.P=10,800$

$C.P=\frac{10800\times 100}{90}$

$\therefore C.P=12,000$

Gain has to be $5\%$

$5\%$ of C.P$=\frac{5}{100}\times 12000=600$

This selling price should be $12,000+600=$Rs. $12,600$/-
