**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**

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**

**Q8. I. 2x² - 12x + 16 = 0 **

**II. y² - 9y + 20 = 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**

⇒ 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**

⇒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
