Correct Answer - Option 2 : 7.14%

**Given:**

Ramesh bought 5 chocolate for Rs. 2. And sold 7 chocolate for Rs. 3

Formula used:

Profit% = (S.P – C.P/C.P) × 100

Calculation:

Ramesh spend Rs.2 for 5 chocolate

And sold for Rs. 3 for 7 chocolate.

To compare we make chocolate equal.

Multiply C.P by 7

⇒ (2 → 5) × 7

⇒ 14 → 35

Multiply S.P by 5

⇒ (3 → 7) × 5

⇒ 15 → 35

⇒ profit = 15 – 14 = 1

⇒ profit% = (1/14) × 100 = 7.14%

**∴ The profit% made by 7.14%.**
