He withdrew Rs.300 on 3rd June, 1997 and after that he neither deposited nor withdrew any money during June 197. What is the amount on which he would receive the intere.st of : (i) May 1997 ? (ii) June 1997?

Answer:

(i) The amount on which he would receive interest for May 1997 = Nil i.e. Rs. 0

Reason :

Whenever an account, with the bank, is opened after 10th of any month; the amount qualifying for interest for that month is Rs. 0.

(ii) The amount on which he would receive the interest of June 1997 = Rs. 550

Reason :

Up to 3rd June, 1t997, the amount to his credit = Rs. 850

On 3rd June, 1997, he withdrew Rs. 300.

Therefore From 3rd June, 1997 to the last day of June, 97 the minimum amount to his credit = 850 – 300 = Rs. 550.

Therefore On 10th June, 1997 and up to the last day of June, 97 the minimum amount to his credit = Rs. 550

Therefore the amount qualifying for interest for the month of June, 97 = Rs. 550
