Solution :


Let Marked Price = MP

By given information saving Rs 15 is 20% of marked price i-e

15=\frac{20}{100} MP

so, \Rightarrow MP=\frac{1500}{20}

 hence, \Rightarrow MP=75

We use the formula for marked price ;

Discount = Marked Price - Selling Price


D = MP - SP

so, from this we can find SP

\Rightarrow SP= MP-D

Since discount is Rs 15 and MP is 75 as we calculated above;

hence, \Rightarrow SP= 75-15= Rs 60

So, Rs 60 were paid
