Step-by-step explanation:

Let his income is x

Then his spending is 75% of x i.e. 0.75x and saving is 0.25x . Now his income is increased by 20% then his new income will be x+(.2x)=1.2x. His spending is increased by 10 % then his new spending will be (.75x)*10/100 + (.75x)=(.825x)

New saving =new income - new spending =1.2x - 0.825x=0.375x

So increase in savings= new savings-old saving=0.375x-0.25x= 0.125x

% increase in saving =( 0.125x/.25x )*100 %=50.0%
