Question

3. Javed deposited 12000 rupees at 9 p.c.p.a. in a bank for some years, and withdrew his
interest every year. At the end of the period, he had received altogether 17,400 rupees.
For how many years had he deposited his money ?​

Answer 1

Amount = Principal + Interest ∴17400 = 12000 + Interest ∴Interest = 17400 – 12000 = Rs 5400 ∴ Total interest = (P x R x T)/100 5400 = (12000 x 9 x T)/100 ∴ (5400 x 100)/(12000 x 9) = T ∴ T = 5 yearsRead more on Sarthaks.com - https://www.sarthaks.com/861465/javed-deposited-12000-bank-for-some-years-and-withdrew-interest-every-year-the-the-period
