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.
