Solution

 

S1. Ans.(a)

Sol.

I.6x² + 7x + 2 = 0

6x² + 3x + 4x + 2 = 0

3x (2x + 1) + 2 (2x + 1) = 0

x = (–1)/2, (–2)/3

II. 3y² + 8y + 5 = 0

3y² + 5y + 3y + 5 = 0

y(3y + 5) + 1 (3y + 5) = 0

y=–1,(–5)/3

x > y

 

S2. Ans.(d)
Sol.
I. 7x² – 23x + 6 = 0
7x² – 21x – 2x + 6 = 0
7x (x – 3) – 2 (x – 3) = 0
x=3,2/7

II. y² – 7y + 12 = 0
y² – 3y – 4y + 12 = 0
y(y – 3) – 4 (y – 3) = 0
y = 3, 4
y ≥ x

 

S3. Ans.(e)
Sol.
I. 5x² + 13x – 6 = 0
5x² + 15x – 2x – 6 = 0
5x (x + 3) – 2 (x + 3) = 0
x=2/5, –3

II. 2y² + 13y – 7 = 0
2y² + 14y – y – 7 =0
2y ( y + 7) – 1 (y + 7) = 0
y = –7, 1/2

No relation

 

S4. Ans.(c)
Sol.
I. 4x + 3y = 4 …(i)
II. 6x + 5y = 8 …(ii)
Multiplying (i) by 5 and (ii) by 3 & subtracting (ii) from (i), we get
x = –2
put x=-2 in (i), we get
y = 4
y > x

 

S5. Ans.(a)
Sol.
I. x² – 19x + 88 = 0
x² – 11x – 8x + 88 = 0
x (x – 11) – 8 (x – 11) = 0
x = 8, 11

II. y² + y – 56 = 0
y² + 8y – 7y – 56 = 0
y (y + 8) – 7 (y + 8) = 0
y = 7, – 8
x > y
