You are depositing Rs. 3 in first day and Rs. 3 in second day in your account. And you are withdrawing Rs. 4 from your account in Third day. You do this repeatedly. When soon do you have Rs. 60 in the account?

On every third day you will have Rs.2 in your account (3+3-4).

Thus you would have reached Rs. 60 in (60/2)*3 = 90 days, but important thing to notice is that you are withdrawing Rs. 4 on every third day.

So your balance will reach Rs.60 mark earlier than that. If we observe we will reach (60-6)=Rs.54 in (54/2)*3=81 days, and as you will deposit Rs.6 in next two days, you will reach Rs.60 in 83 days.
