S6. Ans.(c)

Sol.

  1. 6x² – 9x + 10x – 15 = 0

3x(2x – 3) + 5 (2x – 3) = 0

(3x + 5) (2x – 3) = 0

  1. 4y² – 24y + 35 = 0

4y² – 14y – 10y + 35 = 0

2y (2y – 7) – 5 (2y – 7) = 0

(2y – 7) (2y – 5) = 0

∴ y > x

 

S7. Ans.(e)

Sol.

  1. 5x² + 11x + 2 = 0

5x² + 10x + x + 2 = 0

5x(x + 2) + 1 (x+ 2) = 0

(x + 2) (5x+ 1) = 0

  1. 6y² + 11y + 4 = 0

6y² + 8y + 3y + 4 = 0

2y (3y + 4) +1 (3y + 4) = 0

(3y + 4) (2y + 1) = 0

∴no relation

 

S8. Ans.(a)

Sol.

  1. 2x² – 23x + 56 = 0

2x²– 7x – 16x + 56 = 0

x(2x – 7) – 8 (2x – 7) = 0

(x – 8) (2x – 7) = 0

  1. 3y² – 14y + 15 = 0

3y² – 5y – 9y + 15 = 0

y(3y – 5) -3(3y -5)= 0

∴ x > y

 

S9. Ans.(a)

Sol.

  1. 7x + 2y = 12 …(i)
  2. 4x + 3y = 5 …(ii)

Multiplying (i) by 3 and (ii) by 2 & solving

x = 2, y = -1

x > y

 

S10. Ans.(b)

Sol.

  1. x² + 13x + 40 = 0

x² + 8x + 5x + 40 = 0

x(x + 8) +5(x + 8) = 0

(x + 8) (x + 5) = 0

x = -5, -8

  1. y² + 17y + 72 = 0

y² + 8y + 9y + 72 = 0

y (y + 8) + 9 (y + 8) = 0

⇒ y = -8, -9

x≥y
