Directions (Q. 1 -5) : In of these questions, two equations I and II with variables x and y are given. You have to solve both the equations to find the values of x and y mark answer if
1) If x > y
2) If x >= y
3) If x < y
4) If x <= y
5) If x = y or the relationship can't be established.
1.
I. √x - √8/√x = 0
II. y^3 – (8)^3/2 = 0
2.
I. √(x + 7) = √144 - √49
II. y^2 + 188 = 512
3.
I. 4x – 2y = 10
II. x – y = 3
4.
I. y^3 – 500 = 1228
II. x^2 – 500 = –211
5. I. y^2 – 15y + 56 = 0
II. x^2 + 10x + 21 = 0
