Suman saves 10% of her monthly salary. Now her expenditure increases by 30% and savings increases by 50%. What is the percentage increase in her salary?
║⊕ANSWER⊕║
Let's Suman's monthly salary be Rs.100
She saves 10% of her salary
i.e. 10% of 100 = 10
Also her expenditure = 100-90
= 90 or 90%
According to the question
When expenditure is increased by 30%
such that, 90+(30% of 90) = 90+[(30/100)×90]
= 117
Savings increased by 50%
=> 10+(50% of 10)
= 10+[(50/100)×10)
= 15
New salary = expenditure + savings
= 117+15
= 132
Increase in salary = old salary - new salary
= 132-100
=32
Ans - 32%
the increase in salary is 32%
