Mr. Ramesh opened a recurring deposit account in a bank. He deposited in the installment of ₹1500 per month for two years. At the time of maturity he received an amount of ₹56,000. Calculate the total interest earned by Mr. Ramesh.
Monthly installment = ₹ 1500
n = 2 x 12 = 24 Months
Amount deposited = 1500 × 24 = ₹36000
Maturity value = ₹56000
∴ Interest on his deposit = ₹(56000 – 36000) = ₹20000
