Question

what will be the compound interest on rupees 20000 for 9 months and 8% per annum compounded quarterly 3 months

Answer 1

principal=2000
time=9months=3 quarters
so the rate=8%=8*1\4=4%
amount =apply the formula
a=P(1-r\100)apply the time as power
a=2000(1-4/100)^3
a=2000(1-1/25)^3
a=2000(26/25)^3
a=2000x26/25x26/25x26/25
a=2249.728
