Question no – (1)
Solution :
We know that,
(i) The interest is computer month wish on the minimum balance between the 10th day and the last day of the month.
(ii) The deposits made after 10th day do not earn any interest for that month.
∴ Minimum balance during June (after 10th June) is Rs. 500 and during July is Rs. 1500
∴ Total,
