A bill of 3 months for Rs. 20, 000 was dishonoured on the due date. The drawee paid 40% amount in cash and for the balance, he accepted a two months bill along with 18% interest. Calculate the amount of new bill.

Total amount due = Rs. 20, 000             Paid in cash = Rs. 8, 000             Balance = Rs. 12, 000             Interest = 12,000*18%*2/12 = Rs. 360             Amount of bill = 12000 + 360= Rs. 12, 360 If the new bill is for 3 months, then its amount will be Rs. 12, 540 If the new bill is 8000 + Interest, then its amount will be Rs. 8,240 for 2 months bill and Rs. 8,360 for 3 months bill.
