Question

A shopkeeper earned a profit of $5$ by selling a television for $Rs8500$. Find the cost price of the television.

Answer 1

$S.P=[\frac{(100+Gain\%)}{100}\times G.P]$

$8500={\left(\frac{100+5}{100}\right)}^8\times C.P$

$\frac{8500}{105}\times 100=C.P$

$80.95\times 100=C.P$

$\therefore C.P$ of $T.V\Rightarrow Rs8095$
