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.

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

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

∴ When S.P. is Rs.1, then M.P. =

∴ When S.P. is Rs.1600, then M.P. =

= Rs.2,000
