Sameer had taken some loans from Ravi on simple interest at 11% per annum. After 4 years he returned the loan and the interest by paying Rs.7,200. How much interest did he pay?

- Rs.4,032
- Rs.2,200
- Rs.3,168
- Rs.1,032

**Answer: (2) Rs.2,200**

**Explanation:-**

** Given-**

Principal = ?, Amount = Rs.7,200 , time = 4 years, rate = 11 %

**Formula-**

**Simple Interest = P x R x T/100**

**Where, P – principal, R – rate & T – time.**

S I = P x 11 x 4/100

S I = P 11/25

7200 = P + 11 P/25

7200 = (25 P + 11 P)/25

7200 x 25 = 36 P

P = 200 x 25

P = 5000

Then, S I 72,00 – 5000

= Rs.2,200

Hence, the answer is (2) Rs.2,200
