question_answer 15)

                Arun bought a pair of skates at a sale where the discount given was 20%. If the amount he pays is  Rs 1,600, find the marked price.

Answer:

                100 ? 20 = 80 \[\because \]     If amount paid is Rs 80, then the marked price = Rs 100 \[\therefore \] If amount paid is Rs 1, then the marked price = Rs \[\frac{100}{80}\] \[\therefore \] If amount paid is Rs 1600, then the marked price \[=\frac{100}{80}\times 1600\] = Rs 2000 Hence, the marked price of the pair of skates is Rs 2000.
