Multiple choice

In each question two equations numbered I and II are given, you have to solve both the equation and choose the correct answer. (I.) (x^2 - 20x + 91 = 0 ) (II.) (2y^2 - 55y + 378 = 0)

  1. $\(X > Y\)$
  2. $\(X < Y\)$
  3. $\(X ≤ Y\)$
  4. $\(X ≥ Y\)$

  5. X = Y or the relationship can’t be established

B Correct answer
Explanation

Solving I gives x = 13 and x = 7. Solving II gives y = 14 and y = 13.5. Comparing: 7 < 13.5, 7 < 14, 13 < 13.5, and 13 < 14. All x values are less than all y values, so x < y is correct.
