A shopkeeper fixes the marked price of an item 50% above its cost price. The percentage of discount allowed to gain 20% isQuestion Description : 20%30%25%35%

The problem is asking for the percentage of discount a shopkeeper can give to still gain a profit of 20% if the marked price is 50% above the cost price. Here's how you can solve it:

Step 1: Let's assume the cost price of the item is $100.

Step 2: According to the problem, the shopkeeper marks up the price by 50%. So, the marked price of the item is $150 ($100 + 50% of $100).

Step 3: The shopkeeper wants to gain 20% profit. So, the selling price should be $120 ($100 + 20% of $100).

Step 4: Now, we need to find out how much discount the shopkeeper can give on the marked price to sell the item for $120. The difference between the marked price and the selling price is$30 ($150 -$120).

Step 5: To find the percentage of the discount, we divide the discount by the marked price and multiply by 100. So, the discount percentage is 20% ($30/$150 * 100).

So, the shopkeeper can give a 20% discount on the marked price to gain a 20% profit.
