Question

X's salary is half that of Y's. If X got a 50% rise in his salary and Y got 25% rise in his salary, then the percentage
increase in combineu salaries of both is​

Answer 1

The percentage   increase in combined salaries of both is 33.33%

Step-by-step explanation:

Let the salary of X be a

and X's salary is half of Y

i.e a = $\frac{1}{2}\times Y$

Y = 2a

salary of Y is 2a

new salary of X = (100+50)% of a

= 150% of a

= $\frac{150}{100}\times a$

= $\frac{3}{2} a$

new salary of Y = (100+25)% of 2a

125% of 2a

= $\frac{125}{100}\times 2a$

= $\frac{5}{2} a$

total combined salary of both = ($\frac{3}{2}a +\frac{5}{2} a$) = 4a

therefore,

required increase in combined salary of both = $\frac{a}{3a}\times 100$

= $\frac{100}{3}$

= 33.33%

hence,

The percentage   increase in combined salaries of both is 33.33%
