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
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 determined.
I. x^2 + x – 20 = 0
II. y^2 + 13y + 40 = 0
I. x^2 – 11x + 30 = 0
II. y^2 – 13y + 40 = 0
I. x^2 + 10x + 25 = 0
II. 5y^2 – 2 15 y + 9 = 0
I. 10x^2 – 29x – 21 = 0
II. y^2 + 13y – 68 = 0

1) 11.45
2) 12.45
3) 13.45
