Question

A shopkeeper marks the price of an article at Rs. 1200. Find the selling price, if he allows:
two successive discounts of 15% and 10%.

Answer 1

M.P. = Rs.1200
S.P. = `(1 - "d"_1/100)(1 - "d"_2/100)` of M.P.

⇒ S.P. = `(1 - 15/100)(1 - 10/100) xx 1200`

⇒ S.P. = `(85)/(100) xx (90)/(100) xx 1200`

⇒ S.P. = Rs.918.
