Overdraft questions are where most marks are lost, because every rule from the favourable case reverses.
The problem. On 30 June the pass book shows an overdraft of ₹25,000. You find:
- (a) Cheques issued for ₹8,000 have not been presented.
- (b) Cheques of ₹15,000 deposited have not been collected.
- (c) Interest on the overdraft of ₹900 has been charged by the bank only.
- (d) A cheque received for ₹2,700 was entered in the cash book as ₹7,200.
Find the balance as per the cash book.
The safe method: treat an overdraft as a negative number. Then the favourable-balance logic still works without reversing anything by memory.
- Pass book balance = −25,000
- (a) The cash book has already deducted the cheques issued and the bank has not, so the cash book is lower: −8,000
- (b) The cash book has already added the deposits and the bank has not, so the cash book is higher: +15,000
- (c) The bank has deducted interest and the cash book has not, so the cash book is higher: +900
- (d) The cash book recorded ₹4,500 more than was received, so it is higher: +4,500
Cash book balance = −25,000 − 8,000 + 15,000 + 900 + 4,500 = −12,600, an overdraft of ₹12,600 as per the cash book.
Set out in the overdraft format:
| Particulars | ₹ | ₹ |
|---|
| Overdraft as per pass book (Dr) | | 25,000 |
| Add: Cheques issued, not presented | | 8,000 |
| | 33,000 |
| Less: Cheques deposited, not collected | 15,000 | |
| Interest on overdraft, not in cash book | 900 | |
| Receipt overstated in cash book | 4,500 | 20,400 |
| Overdraft as per cash book (Cr) | | 12,600 |
Notice why the unpresented cheques are added here: starting from the bank's overdraft, they make the cash book more overdrawn than the bank's figure. In the favourable example they were added for a different reason, because they left the bank's balance higher than the cash book's. Work with signed numbers and you never have to reason that out under exam pressure.
