Question

Mohan bought a trouser at 10% discount and sold it to Sohan at a loss of 10%. If Sohan paid Rs. 729 for the trouser to Mohan, then what was the undiscounted price of the trouser?

Accepted Answer

A. Let $P$ be the original undiscounted price. - Mohan bought it at a 10% discount $\implies 	ext{Cost Price for Mohan} = 0.9P$. - Mohan sold it at a 10% loss $\implies 	ext{Selling Price} = 0.9 	imes 0.9P = 0.81P$. Given $0.81P = 729 \implies P = \frac{729}{0.81} = 900$. Undiscounted price = Rs. 900.
