#### Solution

Given that Recurring deposit per month =Rs 900, Period= 3 years = 36 Months, R=8 %

Money deposited= Monthly value x No of Months

= 900 x 36 = Rs 32,400 ...... (1)

Total Principal for 1 Month=Rs (900 xx (36)(36 + 1))/2 = Rs 599400

Interest = Rs (8 xx 599400)/(12 xx 100) = Rs 3996  .......(2)

Hence Maturity Amount= (1) + (2)

=Rs (32,400 + 3,996)

Hence Maturity Amount= Rs 36,396

And Interest= Rs 3,996
