Ankita invested Rs. 1800 at an annual interest rate of (a + 5)%, and she earned a total interest of Rs. 1404 after three years. Now, if she decides to invest the same amount in another account at an annual interest rate of 'a%', but this time for a duration of 2 years, how much interest will she earn in this scenario?
ATQ, 1800 × (a + 5)/100 × 3 = 1404 Or, 18a = 468 – 90 Or, a = 21 Desired Interest = 1800 × (21/100) × 2 = Rs. 756
