Correct Answer - Option 3 : 783
Given:
Average monthly savings during May = Rs. 750
Average monthly savings during June = Rs. 824
Average monthly savings during July = Rs. 775
Concept used:
Average = sum of months / number of months

The average monthly savings for the three months = (750 + 824 + 775)/3 =783
⇒ Rs. 783
∴ The average monthly savings for the three months is Rs. 783.
