A shopkeeper marks the price of an article at Rs. 80. What will be the selling price, if he allows two successive discounts at 5% each = ?

Solution (By Examveda Team)

Marked price of article = Rs. 80
$$\eqalign{ & {\text{Two successive discount }} \cr & {\text{ = 5}} + 5 - \frac{{5 \times 5}}{{100}} \cr & = 10 - 0.25 \cr & = 9.75\% \cr & {\text{Discount of article }} \cr & {\text{ = 9}}{\text{.75% of 80}} \cr & {\text{ = }}\frac{{9.75}}{{100}} \times 80 \cr & = {\text{Rs}}{\text{. 7}}{\text{.80}} \cr & {\text{Selling price of article }} \cr & {\text{ = }}80 - 7.80 \cr & {\text{ = Rs}}{\text{. 72}}{\text{.20}} \cr} $$
