Question

Vishal deposited rs.200 per month for 5 years in a recurring deposit account in post office. of he received rs.13830 find the rate of deposit

Answer 1

Time = 5 years which is equal to 60 months

The amount would be = 200 x 60 x 61/2 = 366000

Now we will assume the rate of interest to be r%

Simple Interest = 366000 x r x 1 / 100 x 12

= 305 r

Principal = 200 x 60

= Rs. 12000

Amount = Rs. 13830

Simple Interest = Rs. 1830

305 r = 1830

= 6

R = 6%
