Answer 1

Answer:

By subtracting the Rs.5760 and Rs. 6912, we get the simple interest amount for one year.

6912–5760 = 1152.

Simple interest amount for two years is 2*1152 = 2304.

Simple interest amount for three years is 3*1152 = 3456.

Principle Amount = Total Sum(Maturity Amount) - Simple interest amount.

5760 - 2304 = 3456 or 6912–3456 = 3456.

Rate of Interest:

S.I = PTR/100

R = S.I *100/PT

R = 1152*100/3456*1 = 33.33%
