Let 100Rs=income
then expenditure is 90Rs and saving is 10Rs
now saving is increased by 50%=5Rs
and expenditure by 30%=27Rs
27+5=32.

Let's Suman's monthly salary is 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

and savings increased by 50%
such that, 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

In %age, (32/100)×100 = 32%
Hence option (c) I is correct
