Simple Interest

Question:

Reena took a loan of Rs.1200 with simple interest for as many years as the rate of interest is. If she paid Rs.432 as interest at the end of the loan period, what was the rate of interest?

Options:

6%

8%

9%

5%

Correct Answer:

6%

Explanation:

Let rate = R% and

time = R years.

Then,  \(\frac{1200 × R × R}{100}\) = 432

12R2 = 432

 R2 = 36

 R = 6%
