Given:
Present value= ₹ 6000
Interest rate= 9% per annum
Time=2 years
To find the amount we have the formula,
Amount (A) = P (1+(R/100))n
Where P is present value, r is rate of interest, n is time in years.
Now substituting the values in above formula we get,
∴ A = 6000 (1 + 9/100)2
⇒ A = 6000 (109/100)2
⇒ A = 6000 (1.09)2
⇒ A = 7128.6
⇒ A = ₹ 7128.6
∴ Compound interest = A – P
= 7128.6 – 6000= ₹ 1128.6
