A man saves an average of Rs. 500 per month from January to June. In July, he saves Rs. 450. From August to December, his total savings are 60 per cent of his savings from January to July. What is his average monthly salary for the year if his average monthly spending for the whole year is Rs. 440? Correct Answer Rs. 900

Given:

A man saves an average from January to June = 500 rupees

Concept:

Income = Expenditure + Saving

Formula used:

Average = (The sum of all items)/(The total number of items)

Calculation:

⇒ The total saving from January to June = 500 × 6 = 3000

⇒ The total saving of January to July = 3000 + 450 = 3450

⇒ The total saving of August to December = 3450 × (60/100) = 2070

⇒ The total saving of whole year = 3450 + 2070 = 5520

⇒ The total spending of whole year = 440 × 12 = 5280

⇒ The total annul income of the man = 5520 + 5280 = 10800

⇒ The total monthly income of man = 10800/12 = 900

∴ The required result will be 900.
