Compound interest formula is
A = P(1 +r/n)^nt
where A = Amount
P is principle in this case its 1000
r rate of interest in decimal (so 5.6% is 0.056)
n - number of years the interst is compounded - in this case its annually so n =1
t is time in this case 3

Manasi_sh, I agree with ri2007! But for me, its very tough to remember the formula at all. So what I would do here is - to solve the prob step-by-step. Like -
After 1st yr : Total amt = 1000 * 105.6/100
After 2nd yr : Total amt = 1000 * 105.6/100 * 105.6/100
After 3rd yr : Total amt = 1000 * 105.6/100 * 105.6/100 * 105.6/100
= 1000 * (1.056)^3
After 1st yr : Total amt = 1000 * 105.6/100
After 2nd yr : Total amt = 1000 * 105.6/100 * 105.6/100
After 3rd yr : Total amt = 1000 * 105.6/100 * 105.6/100 * 105.6/100
= 1000 * (1.056)^3
Correct me If I am wrong
