Question
Sonia had a recurring deposit account in a bank and deposited Rs. 600 per month for 2 1/2 years. If the rate of interest was 10% p.a., find the maturity value of this account.
Solution
Given: P = Rs. 600, n 30months and r = 10%
∴ I = `Rs(600 xx (30(30+1))/(2xx12) xx 10/100) = Rs 2325`
Since sum deposited = P x n = Rs. 600 x 30 Rs. 18000.
Thus, the maturity value Rs. (18000 + 2325) = Rs. 20325
