Question

find compound intrest and amount
(b) Principal = 8000, Rate = 8% p.a., Time = 2whole1/2 years
​

Answer 1

ANSWER

Given Principle P=Rs.8000

Time t=121=23years

But, as the interest is compounded half yearly t=23×2=3years

Rate of interest R=10%

A=P(1+100R)t

A=8000(1+10010)3

A=8000(100110)3

A=8000×(1.1)3

this is your right answer =A=8000×(1.1)3
