Answer:

Correct Answer: D

Solution:

Let the income of man initially be Rs. 100. Expenditure = Rs. 75

$ \therefore $ Savings = Rs. 25 Now, increased income = 120% of 100 $ =\frac{120}{100}\times 100=Rs\text{. 120} $ Increased expenditure = 110% of 75 $ =\frac{110}{100}\times 75=Rs\text{. 82}\text{.5} $ New savings $ =Rs\text{. 120}-82\text{.5= Rs}\text{.}37\text{.5} $

$ \therefore $ Percentage increase in savings $ =\frac{37.5-25}{25}\times 100=50 $ %
