Answer:

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%.
