Question

10. A book bought for 105.00 is sold at a gain of 20%. Find the selling price.​

Answer 1

$\large\sf\underline{Given}$

• Cost price ( CP ) = Rs 105.00 oR Rs 105 .

• Gain = 20 %

$\large\sf\underline{To\:find}$

• Selling Price oR SP

$\large\sf\underline{Solution}$

We know,

$\small{\underline{\boxed{\mathrm\pink{SP=(\frac{100+gain}{100})\times CP}}}}$

$\sf\:⟹\:SP=(\frac{100+20}{100}) \times 105$

$\sf\:⟹\:SP=\frac{120}{100} \times 105$

$\sf\:⟹\:SP=\frac{12600}{100}$

$\sf\:⟹\:SP=\frac{126}{1}$

$\small\fbox\red{⟹\:SP\:=\:Rs\:126}$
