Simple interest (S.I) = 25% × Principal
Time = 5 years
Formula used:
Simple interest (S.I) = (P × R × T)/100
Where, P = principal ; R = rate ; T = time
Calculation:
Simple interest (S.I) = (P × R × T)/100
⇒ 25/100 × P = (P × R × 5)/100
⇒ 25 = R × 5
⇒ R = 5%
According to the question:
Simple interest (S.I) = (P × R × T)/100
⇒ P = (P × 5 × T)/100
⇒ T = 100/5 = 20 years
∴ The correct answer is 20 years.
