1. 6923
2. 7923
3. 8923
4. 9923

Answer 1

Correct Answer - Option 3 : 8923

Given:

Amount in bank = Rs. 7968

The amount deposited every Monday and Tuesday = Rs. 95

The amount deposited every Friday and Saturday = Rs. 85

The amount Withdrawal every Wednesday and Thursday = Rs.75

Calculation:

Mon	Tues	Wed	Thurs	Fri	Sat	Sun
1	2	3	4	5	6	7
8	9	10	11	12	13	14
15	16	17	18	19	20	21
22	23	24	25	26	27	28
29	30	31

Number of Monday and Tuesday = 5 + 5 = 10 

⇒ Total amount deposited on every Monday and Tuesday = 95 × 10 = Rs. 950

Number of Friday and Saturday = 4 + 4 = 8

⇒ The amount deposited on every Friday and Saturday = Rs. 85 × 8 = Rs. 680

Number of Wednesday and Thursday = 5 + 4 = 9

The amount Withdrawal on every Wednesday and Thursday = Rs.75 × 9 = Rs. 675

Amount at the end of month in bank account = 7968 + 950 + 680 - 675 = Rs. 8923

∴ Amount at the end of month in bank account is Rs. 8923.

The correct option is 3 i.e. Rs. 8923
