let the selling price is 100 rupee
on giving 25 % discount the price will be 75,on selling the object in 75 rupee profit = 25 % so original cost will be 75*100/125 = 60
now on giving 10 % discount selling cost will be 90 it means 30 rupee gain on an investment of 60 rupee so profit on investment = 30*100/60 = 50 % (correct answer)
