Given:
Time = 2 years, Simple Interest = 500, rate = 10%
Formula used:
Simple Interest = (Principal × Rate × Time)/100
Compound Interest = Principal[(1 + rate/100)t – 1]
Calculation:
Let the principal be ‘P’.
Simple Interest = (Principal × Rate × Time)/100
⇒ 500 = (Principal × 10 × 2)/100
⇒ Principal = 2500
Compound Interest = Principal[(1 + rate/100)t – 1]
⇒ 2500[(1 + 10/100)2 – 1]
⇒ 525
∴ The compound Interest is Rs 525.
