Performance in manner or at time prescribed or sanctioned by promisee

(a) B owes A 2,000 rupees. A desires B to pay the amount to A‟s account with C, a banker. B, who also banks with C, orders the amount to be transferred from his account to A‟s credit, and this is done by C. Afterwards, and before A knows of the transfer, C fails. There has been a good payment by B.

(b) A and B are mutually indebted. A and B settle an account by setting off one item against another, and B pays A the balance found to be due from him upon such settlement. This amounts to a payment by A and B, respectively, of the sums which they owed to each other.

(c) A owes B 2,000 rupees. B accepts some of A‟s goods in reduction of the debt. The delivery of goods operates as a part payment.

(d) A desires B, who owes him Rs. 100, to send him a note for Rs. 100 by post. The debt is discharged as soon as B puts into the post a letter containing the note duly addressed to A.
