alongwith the affidavit as also the affidavit of evidence sworn by Shri Pukhraj Chhogmal Shah dated 12th July, 2007. Besides the said Pukhraj Chhogmal Shah has appeared in court to give evidence. His evidence has been recorded in court. He has reiterated the stand taken in the affidavit of evidence which is to support the claim in the suit. Besides, he has proved all the relevant documents including the promissory notes. He has also proved the fact that legal notice was sent to the defendants to repay the outstanding amount but the defendants except paying a sum of Rs.31,000/- have remained defaulters. The plaintiff has given credit for repayment of the said amount of Rs.31,000/- in the books of accounts for the period between 3rd November, 1986 to 22nd October, 1987. Inspite of that, the defendants are liable to pay a sum of Rs.2,27,000/- to the plaintiff as would appear from the books of account as on 15th February, 1990. As the evidence of the plaintiff has remained unchallenged and the claim of the plaintiff is supported by the proved documents, this court has no option but to decree the suit in terms of prayer clauses (a) to (e) reproduced earlier. It cannot be doubted that the outstanding payment payable by the defendants to the plaintiff is on account of commercial transaction between them. The plaintiff has substantiated its stand that the agreed rate of interest is 15% per annum.
