### Question 4

Mr. X puts an amount of Rs. 800 in a simple interest scheme. If he gets a total amount of Rs. 1448 after 9 months, what is the rate of interest?

**A**

${3/4}$% p.a.

**B**

9% p.a.

**C**

${11/12}$% p.a.

**D**

1% p.a.

**Soln.**

**Ans: a**

The interest is I = 1448 - 800 = 648. So R = $(I × 100)/(T × P)$. Solving, we get R = $(648 × 100)/(9 × 800)$ = 9% per month, which is ${3/4}$% per annum. *Please note that since the time is in months the rate is also p.m.*
