Directions (6-10): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer

Q6. I. 5x+7y=339
II. 7x+5y=321
if x>y
if x<y
if x≥y
if x ≤y
if x = y or no relationship can be established
Solution:
x + y = 55 ………..(a)
On subtracting both equations
y - x = 9 ……..(b)
From (a) and (b),
x = 23, y = 32
∴ x < y

Q7. I. x² - 18x +77 = 0
II. 3y² - 25y + 28 = 0
if x>y
if x<y
if x≥y
if x ≤y
if x = y or no relationship can be established
Q8. I. 2x² - 12x + 16 = 0
II. y² - 9y + 20 = 0
if x>y
if x<y
if x≥y
if x ≤y
if x = y or no relationship can be established
Solution:
I.2x² - 8x - 4x + 16 = 0
⇒ 2x (x - 4) - 4 (x - 4) = 0
⇒ x = 4 or 2
II. y² - 5y - 4y + 20 = 0
⇒ y (y - 5) - 4 (y - 5) = 0
⇒ y = 5 or 4
∴ x ≤ y

Q9. I. 4x² = 9
II. 2y² - 9y + 10 = 0
if x>y
if x<y
if x≥y
if x ≤y
if x = y or no relationship can be established
Solution:
I. x² = 9/4
⇒ x = ± 3/2
II. 2y² - 5y - 4y + 10 = 0
⇒ y (2y - 5) - 2 (2y - 5) = 0
⇒ y = 2 or 5/2
∴ x < y

Q10. I. 7x² + 6x - 1 = 0
II. 32y² - 20y + 3 = 0
if x>y
if x<y
if x≥y
if x ≤y
if x = y or no relationship can be established
Solution:
I.7x² + 7x - x - 1 = 0
⇒7x (x + 1) - 1 (x + 1) = 0
⇒ x = -1 or 1/7
II. 32y² - 12y - 8y + 3 = 0
⇒ 4y (8y - 3) - 1 (8y - 3) = 0
⇒ y = 1/4 or 3/8
∴ x < y
