Question

find the compound interest on RS 950 at 10 percent per annum for two years​

Answer 1

Answer:

P = 950

R = 10 %

T = 2 years

we can find amount first by

A = P(1+R/100)²

and than subtract the Principal , that will be out CI ..

mY method :-

we know that successive rate of 10% for 2 years is = 21%

so,

our CI = 950*21/100 = 199.5 (Ans)

Answer 2

Answer:

The required compound interest is Rs.199.50

Step-by-step explanation:

P = principal

R = rate of interest per cent per year

T = number of years

A = final amount at the end of T years

A = P*(1 + R/100)^T

We have:

P = Rs.950; R = 10 per cent per year; T = 2 years

=> A = 950*(1 + 10/100)^2

        = 950*(1.1)^2

         = 950*1.21

         = 1149.50

The final amount at the end of two years is Rs.1149.50. This includes the original principal and the compound interest earned.

We want to find only the compound interest, which is A - P

CI = A - P

    = 1149.50 - 950

    = 199.50

The required compound interest is Rs.199.50
