Correct Answer - Option 1 : 2 Years
Given:
R = 25% P.A.
Principal = Rs. 1800
Interest = Rs. 900
Formula used:
S.I. = PRT/100
Where, P = Principal amount, R = Rate of interest, N = Number of years and S.I. = simple interest
Calculation:
According to the question,
Rs. 900 = Rs. (1800 × 25 × T)/100
⇒ 50T = 100
⇒ T = 2 years
∴ The time period of the investment was 2 years
