Question

Every 3 months Tamilselvan deposits Rs 5000 as savings in his bank account. In how many years he can save Rs 1,50,000.

Answer 1

Let the number of years required be x.

Number of months	3 months = \(\frac{3}{12}\times\,150000\) year = 37500	x
Deposit per month in Rs	Rs 5000	150000

No. of years and deposit are direct proportion as they both increases simultaneously.

He can save Rs 1,50,000 in 7\(\frac{1}{2}\) years.
