Question

what is the compound interest on Rs 1600 for 2years at
$2 \frac{1}{2}$
per annum​

Answer 1

Answer:

C.I.= 81

Step-by-step explanation:

Here we have principal(P)= 1600

Rate(R)= 2 1/2= 5/2

Time(T)= 2 years

by using formula to find amount is [A=P(1+r/100)^t]

by putting values A=1600(1+5/2X100)^2

A=1681

We need to find compund interest = C.I.-A(amount )

C.I.=1681- 1600= 81
