Given:

Principal = Rs. 1000

Time = 2 years

Rate of interest = 2%

Formula:

C.I = P × [(1 + r/100)n – 1]

Here,

P = Principal Amount

r = Rate of interest

n = Time in years

Calculation:

We know that -

C.I = P × [(1 + r/100)n – 1]

According to the question,

C.I = 1000 × [(1 + 2/100)2 – 1]

⇒ C.I = 1000 × [(1 + 1/50)2 – 1]

⇒ C.I = 1000 × [(51/50)2 – 1]

⇒ C.I = 1000 × 101/50 × 1/50

⇒ C.I = 40.4

 The Interest Amount will be Rs. 40.4.
