Issues Involved:
1. Validity of the Affidavit-cum-Undertaking dated 13.12.2007.
2. Determination of the actual loan amount.
3. Repayment of the loan amount by the defendant.
4. Application of the principle of res judicata.

Issue-wise Detailed Analysis:

1. Validity of the Affidavit-cum-Undertaking dated 13.12.2007:
The trial court relied on the Affidavit-cum-Undertaking dated 13.12.2007 (Ex.P1) to determine the loan amount. The appellant/defendant no.1 had previously challenged the validity of this document in a civil suit, which was dismissed by the Ld. Civil Judge on 04.07.2013. The judgment from the civil suit was held as final, and the appellant/defendant no.1 was barred by res judicata from questioning the undertaking or the loan amount stated therein.

2. Determination of the Actual Loan Amount:
The trial court concluded that the loan amount was Rs. 6,00,000/- as stated in the Affidavit-cum-Undertaking, and not Rs. 4,10,000/- as contended by the appellant/defendant no.1. This conclusion was based on the document being final and the amount being written by the appellant/defendant no.1 himself.

3. Repayment of the Loan Amount by the Defendant:
The trial court found that the appellant/defendant no.1 had repaid only Rs. 1,30,000/- out of the Rs. 6,00,000/- loan. The court rejected the appellant/defendant no.1's claim of additional payments, including Rs. 18,500/- in cash and Rs. 1,70,000/- paid through demand drafts for the settlement of a cheque issued by his brother. The court held that the payment made for the settlement of the Negotiable Instruments Act case was not towards the loan liability of the appellant/defendant no.1.

4. Application of the Principle of Res Judicata:
The trial court applied the principle of res judicata, stating that the issue of the validity of the Affidavit-cum-Undertaking had already been decided in the previous civil suit, and thus, the appellant/defendant no.1 could not re-litigate this issue.

5. Admissibility of Oral Evidence under Section 92 of the Indian Evidence Act, 1872:
The court held that the contention of the appellant/defendant no.1 regarding an oral agreement to consider the loan amount as Rs. 4,10,000/- instead of Rs. 6,00,000/- was barred by Section 92 of the Indian Evidence Act, 1872. The court emphasized that once a document is taken as final, no oral evidence can alter or modify its terms.

6. Calculation of the Outstanding Loan Liability and Interest:
The trial court calculated the outstanding loan liability as Rs. 4,70,000/- (Rs. 6,00,000/- minus Rs. 1,30,000/-). The court decreed the suit for this amount along with interest at 12% per annum simple. The High Court upheld this calculation and dismissed the appeal, affirming the trial court's judgment.

Conclusion:
The High Court dismissed the appeal, affirming the trial court's judgment that the loan amount was Rs. 6,00,000/-, of which only Rs. 1,30,000/- had been repaid. The remaining balance of Rs. 4,70,000/- was decreed along with interest at 12% per annum simple. All pending applications were also disposed of.
