# Which amount’s interest will be Rs.270 in a period of 6 months with simple interest rate of 9%?

- Rs.5,000
- Rs.4,000
- Rs.7,000
- Rs.6,000

**Answer: (4) Rs. 6, 000**

**Explanation:-**

Let the principal be Rs. X

Given-

Simple interest = Rs. 270, rate = 9% & time = 6 months

270 = X x 6 x 9/12 x 100

30 = 6 X/12 x 100

5 = X/12 x 100

X = 500 x 12

X = 6, 000

Then, the principal is Rs. 6, 000.

Hence, the answer is (4) Rs. 6, 000.
