Question

rupees 18000 for 2 whole no. 1 upon 2 years at 10% per annum compounded annually

Answer 1

Given Principal= P= 18000

Rate of interest Per Annum= i = 10%

Time = n = 2 1/2 = 2.5 years

Lets do it two parts 2 years and half year

Compounded Amount = P(1+i)^n = 18000(1+10/100)^2

= 18000(1 + 0.1)^2

=18000(1.1)^2

=18000(1.21)

= 21780..

For remaining half year ..Rate of interest will be = 10%/2 =5% ..period will be 1

= 21780(1+5/100)^1

= 21780(1 + 0.05)

=21780(1.05)

=22869
