Question Paper from: SBI PO Prelims 2017

I. x² - 7x + 10 = 0

II. y² - 12y + 35 = 0

1:

x = y or no relation can be established

2:

x ≤ y

3:

x ≥ y

4:

x > y

5:

x < y

Solution:
Chapter Name: Quadratic Equation
Difficulty Level: Moderate

x² - 7x + 10 = 0

⇒ x² - 2x - 5x + 10 = 0

⇒ x(x - 2) - 5(x - 2) = 0

⇒ (x - 5)(x - 2) = 0

⇒ x = 5, 2

y² - 12y + 35 = 0

⇒ y² - 5y - 7y + 35 = 0

⇒ y(y - 5) - 7(y - 5) = 0

⇒ (y - 7)(y - 5)

⇒ y = 7, 5

x y
