Question

the amount of on rs 9000 for 18months 8% when compounded galf yearly​

Answer 1

18 months = 1 year + 8 months
So, we have to find compound interest for 1 year and simple interest for 8 months
Simple interest =PNR/100
9000 x 8 x 8 / 100
90 x 64
5760.
Amount = 5760 + 9000 = 14760.

Compound interest = p(1+r/100)^n
= 9000(1+8/100)^1
= 9000(108/100)
= 90 x 108
= 9720

So, 14760 + 9720 = 24480.

Hope this answer will help u!
