HEYYY THERE...

UR ANS IS HERE...

●INCOME =An amount of money which a person earns.

●EXPENDITURE = An amount of money which a person spend for full fill his needs and desires.

●SAVING = An amount of his or her income which he or shedidn't spend , he saves for his or her future .

Lets suppose his income = Rs 100
so his expenditure = 75 % of 100
= Rs.75

Now his income increase by 20%
so , his income = 100 + 20% of 100
= 100 + 20
=Rs.120

nd his expenditure is also increase by 15%
expenditure =75 + 15% of 120
= 75 + 18
= 93

Now we know that
saving = Income - expenditure
= 120 - 93
=Rs 27

saving percent = difference /initial saving ×100
= 27-25/25 ×100
= 2 /25 ×100
= 8%

HOPE IT HELPS U ❤❤

anusingh66666: nd his expenditure is also increase by 15%
expenditure = 75 + 15% of 100
= 75 +15
Rs.= 90 IN THIS STEP WHY 15% IS CALUCLATED ON 100 AND NOT ON 120
