LIC AAO Quantitative Aptitude Quiz: 2nd May |_12.1

Directions (11-15): In the following questions, there are two equations in x and y.
You have to solve both the equations and give answer

Q11. I. x² – 5x – 14 = 0
II. y² – 16y + 64 = 0

if x > y

if x < y

if x ≥ y

if x ≤ y

if x = y or there is no relation between x and y

Solution:

I. x² - 5x – 14 = 0
⇒ x² - 7x + 2x - 14 = 0
⇒ x (x – 7) +2 (x – 7) = 0
⇒ (x - 7) (x + 2) = 0
⇒ x = 7, -2
II. y² - 16y + 64 = 0
⇒ (y -8) ² = 0
⇒ y = 8, 8
= y > x

Q12. I. y² – 7y + 12 = 0
II. x² – 9x + 20 = 0

if x > y

if x < y

if x ≥ y

if x ≤ y

if x = y or there is no relation between x and y

Solution:

I. y² - 7y + 12 = 0
⇒ y² - 4y – 3y + 12 = 0
⇒ (y - 4) (y - 3) = 0
⇒ y = 4, 3
II. x² - 9x + 20 = 0
⇒ x² - 5x – 4x + 20 = 0
⇒ (x - 5) (x – 4) = 0
⇒ x = 5, 4
x ≥ y

Q13. I. 2x² + 11x + 12 = 0
II. 4y² + 13y + 10 = 0

if x > y

if x < y

if x ≥ y

if x ≤ y

if x = y or there is no relation between x and y

Solution:

I. 2x² + 11x + 12 = 0
⇒ 2x² + 8x + 3x + 12 = 0
⇒ (x + 4) (2x + 3) = 0
⇒x= -4 , -3/2
II. 4y² + 13y + 10 = 0
⇒ 4y² + 8y + 5y + 10 = 0
⇒ (y + 2) (4y + 5) = 0
⇒ y=-2, -5/4
No relation

Q14. I. 2x + 3y = 4
II. 3x + 2y = 6

if x > y

if x < y

if x ≥ y

if x ≤ y

if x = y or there is no relation between x and y

Solution:

I. 2x + 3y = 4
II. 3x + 2y = 6
Multiplying equation (i) by 2 and Equation (ii) by 3 and then substracting,
