Answer 1

$\huge{\underline{\bf{Question:-}}}$

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?

$\huge{\underline{\bf{Answer:-}}}$

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 + saving

= 117 + 15

= 132

Increase in salary = old salary - new salary

= 132 - 100

= 32

Therefore, 32% is the correct answer.
