hello mate
Explanation:
He spends 60% of his income. So, expenditure E1=60xE1=60x, [savings S1=40xS1=40x]
His income increases by 15%. So, new income, I2=115xI2=115x
Expenditure increases by 5%. So, 5% increase on 60x60x results in new expenditure E2=63xE2=63x
So, new savings S2=115x−63x=52xS2=115x−63x=52x
So, percentage change in savings can be calculated as:
S2−S1S1×100S2−S1S1×100
=52x−40x40x×10=52x−40x40x×10
=30% (Answer)=30% (Answer)

Considering his income 100.
Expenditure = 60 ,Savings =40
New Income= 115 (15%of 100+100)
Expenditure Increased by 5% means , 5% of 60 +60 = 63
New Savings = 115–63 = 52
New Increase in Savings = 52–40 =12
Increase in %= (12/40) *100 =30%

Let a person has a salary of $1000. Now, his expenditure is 60% that is $600 and rest of the money goes to the saving that is 40 % now as his salary goes 15 % up now his salary is $1150 and expenditure rises by 5%. 5% of total expenditure is $30 and now total expenditure is $630 and saving is $520.
Intially total saving was $400 and now saving is $520. Increase in the saving is $120 which is equal to around 30%
Increase in the saving is around 30%.
