Answer 1

Step-by-step explanation:

answer (C)

A man's average monthly expenditure for the first four months of the year = Rs.231.25.

For four month = 231.25 * 4 = Rs. 925

For next five month he spend = 231.25 + 22.75 for one month.

In five month he spend = (231.25 + 22.75) X 5 = 1270

If the person spent Rs. 605 in all during the remaining three months of the year,

Total expense = 925+1270+605= 2800

Saving = 3500-2800 = 700

% saving = 700/3500 * 100 = 20%
