Correct Answer - Option 1 : Rs. 3600

**Given:**

Rate = 10% per annum

Compound Interest = Rs. 756

Time 2 years

**Formula used:**

Compound Interest = P{1 + (Rate/100)}^{Time} - P

Where, P = Principal

**Calculation:**

By the using formula,

Compound Interest = P{1 + (Rate/100)}Time - P

⇒ 756 = P{1 + (10/100)}^{2} - P

⇒ 756 = P{(11/10)^{2} - 1}

⇒ 756 = P × (21/100)

⇒ P = 36 × 100 = 3600

**∴ The Principal is Rs. 3600**
