Dear Aspirants, Here Find Practice on Quadratic Equation Practice set 4 for IBPS Clerk 2017

1 . Directions (Q. 1 - 5): 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 $x \geq y$
(3) if $x < y$
(4) if $x \leq y$
(5) if x = y or relationship between x and y cannot be established

$Q.$
I.11x + 5y = 117
II. 7x + 13y = 153
 A). $x > y$ B). $x \geq y$ C). $x < y$ D). $x \leq y$

2 . I.$6x^ 2$ + 51x + 105 = 0
II. $2y^ 2$ + 25y + 78 = 0
 A). $x > y$ B). $x \geq y$ C). $x < y$ D). $x \leq y$

3 . I.6x + 7y = 52
II. 14x + 4y = 35
 A). $x > y$ B). $x \geq y$ C). $x < y$ D). $x \leq y$

4 . I.$x^ 2$ + 11x + 30 = 0
II. $y^ 2$ + 12y + 36 = 0
 A). $x > y$ B). $x \geq y$ C). $x < y$ D). $x \leq y$

5 . I.$2x^ 2$ + x - 1 = 0
II. $2y^ 2$ - 3y + l = 0
 A). $x > y$ B). $x \geq y$ C). $x < y$ D). $x \leq y$

6 . Directions (Q.6-10) : In the following questions three equations numbered I, II and III are given. You have to solve all the equations either together or separately, or two together and one separately, or by any other method and give answer If
(1) x < y = z
(2) x < y < z
(3) x < y > z
(4) x = y > z
(5) x = y = z or if none of the above relationship is established

$Q.$
I. 7x + 6y + 4z = 122
II. 4x + 5y + 3z = 88
III. 9x + 2y + z = 78
 A). x < y = z B). x < y < z C). x < y > z D). x = y > z

7 . I. 7x + 6y =110
II. 4x + 3y = 59
III. x + z = 15
 A). x < y = z B). x < y < z C). x < y > z D). x = y > z

8 . I. x = $\sqrt{[(36)^{1\over 2} \times [1296]^{1\over 4}]}$
II. 2y + 3z = 33
III. 6y + 5z = 71
 A). x < y = z B). x < y < z C). x < y > z D). x = y < z

9 . I. 8x + 7y= 135
II. 5x + 6y = 99
III. 9y + 8z = 121
 A). x < y = z B). x < y < z C). x < y > z D). x = y > z

10 . I. $(x + y)^ 3$ = 1331
II. x - y + z = 0
III. xy = 28
 A). x < y = z B). x < y < z C). x < y > z D). x = y = z or if none of the above relationship is established
