(a) 30
(d) 75
(6) 37 1/3​

Answer 1

Answer: 33 1/3

Step-by-step explanation:

Let the salary of X be x and that of Y be y

Then y=2x

Then x+y=x+2x=3x

Increase in x salary=x. 50%=x/2

Increase in y salary=y. 25%=y/4

New salary of x=x+x/2=3x/2

New salary of y=y+y/4=5y/2

Combined salary =3x/2+5y/2=3x/2+5(2x)/4=4x

Increase is 4x-3x=x

% increase is x/3x.100=33 1/3 %
