Introduction:
In this scenario, Mona sold goods to Ram at a list price of 10000 with a 10% trade discount and 2% cash discount. Mona received a cheque from Ram for 40% of the amount, and bank discount was allowed. The question is whether there will be any debit or not.

Trade Discount:
Mona gave a trade discount of 10% to Ram, which means that the list price of the goods was reduced by 10%. So, the net price payable by Ram was 9000 (List Price - Trade Discount).

Cash Discount:
Mona also offered a cash discount of 2% to Ram, which means that if Ram pays the amount within the specified time, he will get a discount of 2% on the net price payable. The net price payable by Ram after the cash discount was 8820 (Net Price Payable - Cash Discount).

Cheque Received:
Ram gave a cheque for 40% of the amount, which means that he paid 3528 (40% of Net Price Payable) to Mona.

Bank Discount:
Mona availed a bank discount on the cheque received from Ram. Bank discount is the interest charged by the bank for discounting the cheque before the due date. The bank discount was not mentioned in the scenario, so it is assumed that Mona availed the bank discount.

Debit or Credit:
As Mona received a cheque from Ram, it means that Ram is liable to pay the remaining amount. The net price payable by Ram after the cash discount was 8820, and he paid 3528 through the cheque. So, the remaining amount payable by Ram was 5292.

As Mona has not received the full payment, she will debit Ram's account for the remaining amount of 5292.

Conclusion:
In conclusion, Mona will debit Ram's account for the remaining amount of 5292 as she has not received the full payment. The sale transaction included a trade discount of 10% and a cash discount of 2%. Mona availed the bank discount on the cheque received from Ram, which was not mentioned in the scenario.

Discount allowed will be debited by 180 Rs.
