Make most of it.

Directions (Q. 1-10): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer

1) if x < y

2) if x > y

3) if x ≤ y

4) if x ≥ y

5) if x = y or no relationship can be established between x and y.

1. I. x2 – 24 x + 144 = 0

II. y2 – 26 y + 169 = 0

2. I. 2 x2 + 3 x – 20 = 0

II. 2 y2 +19 y + 44 = 0

3. I. 6 x2 + 77 x + 121 = 0

II. y2 + 9 y – 22 = 0

4. I. x2 – 6 x = 7

II. 2 y2 + 13 y + 15 = 0

5. I. 10 x2 – 7 x + 1 = 0

II. 35 y2 – 12 y + 1 = 0

6. I. 7 x2 – 33 x + 20 = 0

II. 7 y2 + 9 y – 10 = 0

7. I. 7 x + 3 y = 8

II. 3 x + 2 y = 12

8. I. x2 = 289

II. y = 3√2197

9. I. 8 x2 – 11 x + 3 = 0

II. y2 – 8 y + 7 = 0

10. I. x =√1089

II. y2 + y – 756 = 0
