let cost price is 100rs then marked price will be:175rs so to make no profit or loss the product should be sold at 100rs now discount:175-100=75rs so % discount:(75/175)x100=42.85%

Let 10 be the CP of the goods. So, 75% of 10 is 7.5, then his SP will be 17.5. Therefore, 17.5-(17.5*x/100)=10 x=42.85%

75

Hint:assume 100 as cp, Then,100->175->100 Find % reduction in 175->100.

cp=100 market price=175 discou nt=175-100=75 discount%=75/175*100=42.85%
