Answer 1

Solution :

$\underline{\bf{Given\::}}}}$

• Cost price of a watch, (C.P) = Rs.900
• Shopkeeper sells at a discount = 12%
• Profit, (P) = 10%

$\underline{\bf{Explanation\::}}}}$

Using formula of the marked price according to given above data;

$\boxed{\bf{Maked\:price=\bigg[\frac{100+profit}{100-discount} \times C.P\bigg]}}}$

A/q

$\longrightarrow\sf{Marked\:price=\bigg[\dfrac{100+10\%}{100-12\%} \times 900\bigg]}\\\\\\\longrightarrow\sf{Marked\:price=\dfrac{110}{88} \times 900}\\\\\\\longrightarrow\sf{Marked\:price=\cancel{\dfrac{99000}{88} }}\\\\\\\longrightarrow\bf{Marked\:price=Rs.1125}$

Thus;

The advertised price will be Rs.1125 .
