# Easy Percentages Solved QuestionAptitude Discussion

 Q. If 50% of $x$ equals the sum of $y$ and 20, then what is the value of $x – 2y$?
 ✖ A. 20 ✔ B. 40 ✖ C. 60 ✖ D. 80

Solution:
Option(B) is correct

50% of $x$ equals the sum of $y$ and 20. Expressing this as an equation yields:

$\left(\dfrac{50}{100}\right)×x = y + 20$

$\dfrac{x}{2} = y + 20$

$x = 2y + 40$

$x – 2y =$ 40

0.5x = y+20

(multiply by 2 on both sides)

x=2y+40

x-2y = 40
