Kailash's income = A
Amount spent = expenditures = 85/100 * A
Amount saved = A - 85/100 * A = 15/100 * A
or 15% of income.
New income after the increase: A + 36% * A = 136/100 * A
New expenditure = (85/100 * A) + 40/100 * (85/100 * A)
= 85/100 * A * 140/100 = 119/100 * A
New savings now = income - expenditure
= 136/100 * A - 119/100 * A
= 17/100 * A
So Kailash's savings now are = 17% of his income.

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
