Answer 2

Answer:

30%  per Annum

2.5 % per month

Step-by-step explanation:

We need to find rate of interest

when Rs 2.5 interest is received on a Amount of Rs 100 per month

P = 100

R = Rate of interest per Annum

T = time = 1 Month = 1/12 Year

Simple Interest = 2.5

Simple interest = P * R * T /100

2.5 = 100 * R  * (1/12) /100

=> R = 2.5 * 12

=> R = 30

Rate of interest = 30%  per Annum

if rate of interest = R % per month

then T = 1 month

2.5 = 100 * R * 1/100

=> R = 2.5

2.5 % per month
