Question

Arun bought a pair of skates at a sale where the discount given was 20%. If th amount he pays is 1,600, find the marked price without taking x ​

Answer 1

Solution:

S.P. = Rs.1,600 and Rate of discount

= 20%

Let M.P. be Rs.100, then S.P. for customer

= 100 – 20 = Rs.80

\because When S.P. is Rs.80, then M.P. = Rs.100

\therefore When S.P. is Rs.1, then M.P. = \frac{100}{80}

\therefore When S.P. is Rs.1600, then M.P.

= \frac{100}{80}\times1600=Rs.\ 2000
