QUANTS FOR IBPS CLERK PRE – QUADRATIC EQUATION

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 relation can be established between ‘x’ and ‘y’.

1. 
I. x² + 3 x – 28 = 0
II. y² – 11 y + 28 = 0
2. 
I. 6 x² – 17 x + 12 = 0
II. 6 y² – 7 y + 2 = 0
3. 
I. x = √256 / √576
II. 3 y² + y – 2 = 0
4. 
I. x² = 64
II. y² = 9 y
5. 
I. x² + 6 x – 7 = 0
II. 41 y + 17 = 140
6. 
I. x² + 3 x = 28
II. y²  + 16 y + 63 = 0
7. 
I. x = ³√2197
II. y² = 169
8. 
I. 8 x² – 49 x + 45 = 0
II. 8 y² – y – 9 = 0
9. 
I. 42 x – 17 y = –67
II. 7 x + 12 y = –26
10. 
I. x² – 8 x + 15 = 0
II. 2 y² – 21 y + 55 = 0
