Question

A table was sold for INR $2142$ at a gain of $5\%$. At what price should it be sold to gain $10\%$.

Answer 1

selling price $=2142$

gain$=5$%

let the cost price be $x$

then accourding to question

$=>x+\frac{5x}{100}=2142$

$=>x=\frac{x}{20}=2142$

$=>\frac{21x}{20}=2142$

$=>21x=2142\times 20$

$=>x=2040$

So,the selling price=cost price + gain

$=>2040+\frac{2040\times 10}{100}$

$=>2040+204$

$=>2244$

So,the shopkeeper should sell thee table in rupees $2244$ to get a gain of $10$%
