Quadratic Equation for IDBI Executive 2018: 16 April
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 relationship between x and y cannot be established
2) if x ≥ y
3) if x < y
4) if x ≤ y
5) if x = y or relationship between x and y cannot be established
