Profit = 15% [Selling price is Rs.32 less than marked price]

==> SP at Rs 32 less than MP(marked price) = [(100+gain%)/100]xCP

= (115 / 100) x 320 = Rs.368.

==> MP = 368+32 = Rs.400.

Now if SP = 400 and CP = 320, Then gain = 400 - 320 = 80

Therefore gain % = (profit / CP) x 100 = (80 / 320) x 100 = 25 %
