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
