Correct Answer - Option 1 : 25%

**Given:**

CP of 6 apples = Rs. 24

SP of 4 apples = Rs. 20

**Formula Used:**

Profit Percent = {(SP - CP)/CP} × 100%

Where, SP = Selling Price, CP = Cost Price

**Calculation:**

According to the question,

CP of the apples = (Cost Value of 6 apples)/(Number of apples bought)

⇒ 24/6 = Rs. 4

SP of the apples = (Sale Value of 4 apples)/(Number of apples sold)

⇒ 20/4 = Rs. 5

Profit percentage = {(SP - CP)/CP} × 100%

⇒ {(5 - 4)/4} × 100%

⇒ (1/4) × 100%

⇒ 25%

**∴ His profit percentage is 25%.**
