Directions (Q. 1–4): In each of these questions, two equations numbered I and II with variables x and y are given. You have to solve both the equations to find the value of x and y. Give answer

a) if x > y 
b) if x >= y 
c) if x < y
d) if x <= y 
e) if x = y or relationship between x and y cannot be determined.

1. 
I. x^2 + x – 20 = 0
II. y^2 + 13y + 40 = 0


2. 
I. x^2 – 11x + 30 = 0
II. y^2 – 13y + 40 = 0

3. 
I. x^2 + 10x + 25 = 0
II. 5y^2– √60 y + 3 = 0

4. 
I. 10x^2 – 29x – 21 = 0
II. y^2 + 13y – 68 = 0
