Answer» Correct Answer - Option 2 : 15 Given: Principal(P) = Rs. 7000 Rate of interest(R) = 20% per annum Simple interest = Rs. 1750 Formula used: Simple interest(SI) = \(\dfrac{P \times R \times T}{100}\) Calculation: According to the question: 1750 = \(\dfrac{7000 \times 20 \times T}{100}\) ⇒ T = 175000/140000 ⇒ T = 1.25 years = 15 months ∴ Amount was invested for 15 months |
