Let His Income is Rs. 100 so presently he is spending Rs. 85.
Now his income increased by 36% so his present income is Rs. 136.
His expenditure increased by 40% so his present expenditure is Rs. (85 + 40%of85) i.e. 85 + 34 = Rs. 119
Now his income is Rs. 136 and his expenditure is Rs. 119 so his saving is
136 - 119 = Rs. 17
Therefore saving percent - (17 / 136) * 100 = 12.5% Answer
