In the following question, two equations numbered I and II are given. Solve both equations and mark the appropriate relation between x and y. I. x^2 - 16x + 55 = 0 II. y^2 - 17y + 52 = 0

1. x = y or relationship between x and y cannot be established
2. x ≥ y
3. x < y
4. x << y

Correct answer: x = y or relationship between x and y cannot be established

Solution

Equation I factors as (x - 11)(x - 5) = 0, so x = 11 or 5. Equation II factors as (y - 13)(y - 4) = 0, so y = 13 or 4. Since the possible values overlap in ordering, no definite relation can be established.
