If a discount of 10% is allowed on the marked price of an article, a shopkeeper gets a profit of 25%. If he offers a discount of 25% on the same article, then his profit or loss percent will be:

4\(\frac{1}{6}\)% profit

Let MRP = Rs. 100

SP = 100 × \(\frac{90}{100}\) = Rs. 90

CP = 90 × \(\frac{100}{125}\) = Rs. 72

SP = 100  × \(\frac{75}{100}\) = Rs. 75

Profit % = \(\frac{(75 - 72)}{72}\) × 100 = 4\(\frac{1}{6}\)%
