Question

On selling a mobile for Rs 750, a shop keeper looses 10%. For what amount should he sell it to gain 5%?

Answer 1

According to the problem:

first calculate cost price,

Given That

$SP=750$

Loss$=10\%$

Therefore, CP=SP$+10\%$ of CP
$\Rightarrow CP(1-\frac{10}{100})=SP$
$\Rightarrow CP=SP\times \frac{100}{90}$

$\Rightarrow CP=\frac{750\times 100}{90}$

$=\frac{2500}{3}Rs$

Now, he has to gain $5$ on this cost price,

Therefore, the new selling price would be,

$=\frac{2500}{3}\times \frac{105}{100}$

$=RS.875$

Hence the answer is

$875Rs$
