Sum compounded alluny Shar
d) The difference between the annual and semi-annual compound interest on
of money is Rs 482 at the rate of 20 % per annum for 2 years. Find the sum

Rs 20000

Step-by-step explanation:

Let the sum is x.

The rate of interest, r=20%=0.2

Time, t=2 years.

Total amount after t years,

The value of n when compounded annually, n=1

So, the total amount,

The compound interest when compounded annually,

The value of n when compounded semi-annually, n=2

So, the total amount,

The compound interest when compounded semi-annually,

As the difference between the annual and semi-annual compound interest on  x amount of money is Rs 482, so

x=20000

Hence, the sum is Rs 20000.
