Expert Answer
The man spends 80% of his income
Hence he saves 20% of his income.
His income increased by 25%
Let his present income be 125
His expenditure increased by 10%
10% 0f 80% = 8%
Hence present expenditure is 80 + 8 =88%
if the income is 125, the expenditure is 88
if the income is 100, the expenditure = 100/125 of 88
hence expenditure = 70.4%
hence savings= 29.6%
hence savings increased by 29.6 - 20 = 9.6%
