Direction: In the following questions two equations numbered (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 the relationship can’t be established.

11.
I. x = sqroot(1369)
II. y = cuberoot(29791)

12.
I. 8x – 3y = 31
II. 5x + 4y = 84

13.
I. 20x^2 – 79x + 77 = 0
II. 4y^2 + 9y – 28 = 0

14.
I. 6x^2 + 29x + 28 = 0
II. 6y^2 + 11y + 4 = 0

15.
I. x^2 + 3x – 54 = 0
II. y^2 + 4y – 77 = 0

Answers C, D, B, E, A, C, D, A, B, E,

11. 1;
x = sqroot(1369) = 37……………….. (I)
y = cuberoot(29791) = 31 ………………. (II)
x > y

12. 3;
Equn. (I) ×4 + equn (II) ×3
32 x – 12 y = 124
15 x + 12 y = 252
_____________
47 x = 376
4
x = 8 and from this y = 11
x < y

13. 2;
20 x^2 – 35 x – 44 x + 77 = 0
5 x (4 x – 7) – 11 (4 x – 7) = 0
(4x – 7) (5 x – 11) = 0
x = 7/4, 11/5

4 y^2 + 16 y – 7 y – 28 = 0
4 y (y + 4) – 7 (y + 4) = 0
(4 y – 7) (y + 4) = 0
y = – 4, 7/4
x >= y

14. 4;
6 x^2 + 8 x + 21 x + 28 = 0
2x (3 x + 4) + 7 (3x + 4) = 0
(3x + 4) (2 x + 7) = 0
x = -4/3, -7/2

6 y^2 + 3 y + 8 y + 4 = 0
3 y (2 y + 1) + 4 (2 y + 1) = 0
(3 y + 4) (2 y + 1) = 0
y = -4/3, -1/2
x <= y

15. 5;
x^2 + 9x – 6 x – 54 = 0
x (x + 9) –6 ( x + 9) = 0
x = 6, –9

y^2 + 11 y – 7 y – 77 = 0
y (y + 11) – 7 (y + 11) = 0
(y – 7) (y + 11) = 0
y = 7, –11
i.e. No relation between x & y
