An investor puts an amount of Rs. 2300 in a simple interest scheme. If the rate of interest is 4% per month, how long does he have to wait for getting an amount of Rs. 2944?


${7/12}$ year.


${2/3}$ year.


${3/4}$ year.


${5/6}$ year.

Ans: a

The interest is I = 2944 - 2300 = 644. So T = $(I × 100)/(R × P)$. Solving, we get T = $(644 × 100)/(4 × 2300)$ = 7 months.
