Mr. X had Tk. 1000 in his savings account. Every month in the first week he needs money, so he withdraws Tk. 500, but by the end of the month , he deposits Tk. 750. After how many months, the original amount will grow three times?
- A. 6 months
- B. 6 months
- C. 6 months
- D. 6 months
Answer: Option C
Explanation:
Let, n be the no. of month
Then,
initial deposit-n*Monthly Withdrawal + n*Monthly Deposit =Intial Deposit *3
>1000-n*500 + n*750=3000
>250*n=2000
Therefore, n=8 month
