# Quadratic Equation Questions for LIC Assistant with PDF | LIC Daily Quiz at Smartkeeda

Directions: In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer.
Important for :
1
I. x2 = 49

II. y2 = 16
» Explain it
E
I. x2 = 49

∴ x = ± 7

II. y2 = 16

∴ y = ± 4

Hence, no relationship can be established.

Hence, option E is correct.
2
I. x2 – 13x + 40 = 0

II. y2 – 16y + 63 = 0
» Explain it
E
I. x2 – 13x + 40 = 0

x2 – 8x – 5x + 40 = 0

x (x – 8) – 5 (x – 8) = 0

(x – 8) (x – 5) = 0

x = 8, 5

II. y2 – 16y + 63 = 0

y2 – 9y – 7y + 63 = 0

y (y – 9) – 7 (y – 9) = 0

(y – 9) (y – 7) = 0

y = 9, 7

Hence, no relationship can be established.

Hence, option E is correct.
3
I. x2 + 4x + 3 = 0

II. 5y2 + 8y + 3 = 0
» Explain it
B
I. x2 + 4x + 3 = 0

x2 + 3x + 1x + 3 = 0

x (x + 3) + 1 (x + 3) = 0

(x + 3) (x + 1) = 0

x = – 3, – 1

II. 5y2 + 8y + 3 = 0

5y2 + 5y + 3y + 3 = 0

5y (y + 1) + 3 (y + 1) = 0

(5y + 3) (y + 1) = 0

y = – 0.6, –1,

Hence, x ≤ y

Hence, option B is correct.
4
I. 2x2 – x – 231 = 0

II. 2y2 + 43y + 231 = 0
» Explain it
C
I. 2x2 – x – 231 = 0

2x2 – 22x + 21x – 231 = 0

2x (x – 11) + 21 (x – 11) = 0

(2x + 21) (x – 11) = 0

x = – 10.5, 11

II. 2y2 + 43y + 231 = 0

2y2 + 22y + 21y + 231 = 0

2y (y + 11) + 21 (y + 11) = 0

(2y + 21) (y + 11) = 0

y = – 10.5, –11,

Hence, x ≥ y

Hence, option C is correct.
5
I. 55x2 – 495x + 1100 = 0

II. 5y2 + 10y – 120 = 0
» Explain it
C
I. 55x2 – 495x + 1100 = 0

x2 – 9x + 20 = 0

x2 – 5x – 4x + 20 = 0

x (x – 5) – 4 (x – 5) = 0

(x – 4) (x – 5) = 0

x = 5, 4

II. 5y2 + 10y – 120 = 0

y2 + 2y – 24 = 0

y2 + 6y – 4y – 24 = 0

y (y + 6) – 4 (y + 6) = 0

(y + 6) (y – 4) = 0

y = – 6, 4

Hence, x ≥ y

Hence, option C is correct.
