A man's average monthly expenditure for the first four months of the year was Rs.231.25.
He spent 231.25 * 4 = Rs. 925
For the next five months,the average monthly expenditure was Rs. 22.75 more than what it was during the first four months.

He spends 231.25+22.75 for one month
In 5 months he spends (231.25+22.75) *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 %
find what percentage of his annual income of Rs.3500 did he save in the year?
