cost of clock = x
discount = x X 20/100 = x/5
x/5 = 15
x = 5 x 15 = 75
price of clock before discount = 75
Amount he paid = 75 - 15 = Rs 60

Let the total amount be 'x'.
Given that he saves 15 rupees on purchase, when a discount of 20% is given.
= > x - (20% of x) + 15 = x
= > x - 20% of x = x - 15
= > x - (20x/100) = x - 15
= > (100x - 20x)/100 = x - 15
= > 80x/100 = x - 15
= > 80x = 100(x - 15)
= > 80x = 100x - 1500
= > -20x = -1500
= > x = 1500/20
= > x = 75.
Hence, the amount = 75 - 15 = 60.
Therefore, the total amount he paid = 60 rupees.
Hope this helps!
