Question

Sudhir opened a recurring deposit account with a bank for 1.5 years. If the rate of interest is 10% and
the bank pays ₹1554 on maturity, find how much
did Sudhir deposit per month?​

Answer 1

Answer:

For recurring deposit interest can be calculated using the formula

SI = P * n(n+1)/2*12 * r/100

Where SI is simple interest, P is the the money deposited per month, n is number of months for which money deposited and r is rate of interest per annum.

Therefore,

SI = P * 18(18 + 1)/2*12 * 10/100

= P * (18*19)/(2*12) * 1/10

= P * (3*19)/40

= 57P/40

A = P*n + SI

1554 = 18P + 57P/40

1554 = (720 + 57)P/40

P = 1554*40/777

P = 2*40 = 80

Therefore, Sudhir deposit every month Rs. 80
