Answers :
1) Answer: E
I) 6x2– 29x + 34 = 0
=> (x-2)(6x – 17) = 0
=> x = 2, 17/6
II) 4y2– 13y + 9 = 0
=> (y-1)(4y-9) = 0
=> y = 1, 9/4
Hence, relationship between x and y cannot be determined.
2) Answer: D
I) 2x2+ 17x +33 = 0
=> (x+3) (2x+11) = 0
=> x = -3, -11/2
II) 17y2+ 48y – 9 = 0
=> (17y-3) (y+3)
=> y = 3/17, -3
Hence, x ≤ y
3) Answer: C
I) 9x2+ 81x + 162 = 0
=> x2 + 9x + 18 = 0
=> (x + 6)(x + 3) = 0
=> x = -6, -3
II) 14y2– 132y + 238 = 0
=> 7y2 – 66y + 119 = 0
=> (y – 7)(7y – 17) = 0
=> y = 7, 17/7
Hence, x<y
4) Answer: E
I) 14x2+ 210x + 196 = 0
=> X= 196/14 , 14/14
X=-14, -1
II) 6y2+ 25y + 21 = 0
=> (6y + 7)(y + 3) = 0
=> y = -7/6, -3
Hence, Relationship cannot be established
5) Answer: A
I) 6x2– 32x + 42 = 0
=> (6x – 14)(x – 3) = 0
=> x = 3, 7/3
II) y2 + 7y + 12 = 0
=> (y + 3)(y + 4) = 0
=> y = -3, -4
Hence, x > y
6) Answer: E
2x2 + 32x + 120 = 0
2x2 + 20x + 12x + 120 = 0
2x(x + 10) + 12(x + 10) = 0
(x + 10)(2x + 12) = 0
x = -10, -6
y2 + 16y + 48 = 0
y2 + 12y + 4y + 48 = 0
y(y + 12) + 4(y + 12) = 0
(y + 12)(y + 4) = 0
y = -12, -4
Relationship between x and y cannot be established.
7) Answer: D
x2 – 23x + 102 = 0
x2 – 17x – 6x + 102 = 0
x(x – 17) – 6(x – 17) = 0
(x – 6)(x – 17) = 0
x = 6, 17
y2 – 35y + 306 = 0
y2 – 17y – 18y + 306 = 0
y(y – 17) – 18(y – 17) = 0
(y – 18)(y – 17) = 0
y = 18, 17
x ≤ y
8) Answer: C
3x2 – 15x + 18 = 0
3x2 – 9x – 6x + 18 = 0
3x(x – 3) – 6(x – 3) = 0
(3x – 6)(x – 3) = 0
x = 2, 3
2y2 – 40y + 198 = 0
2y2 – 22y – 18y + 198 = 0
2y(y – 11) – 18(y – 11) = 0
(2y – 18)(y – 11) = 0
y = 9, 11
x < y
9) Answer: B
x2 + 31x + 238 = 0
x2 + 17x + 14x + 238 = 0
x(x + 17) + 14(x + 17) = 0
(x + 14) (x + 17) = 0
x = -14, -17
2y2 + 70y + 612 = 0
2y2 +36y + 34y + 612 = 0
2y(y + 18) + 34(y + 18) = 0
(2y + 34) (y + 18) = 0
y = -17, -18
x ≥ y
10) Answer: E
I) 7x2 + 13x + 6 = 0
7x2 + 7x + 6x + 6 = 0
7x (x + 1) + 6 (x + 1) = 0
= > (7x + 6) (x + 1) = 0
= > x = -1, -6/7
II) 3y2 + 8y + 4 = 0
3y2 + 6y + 2y + 4 = 0
3y (y + 2) + 2 (y + 2) = 0
(3y + 2) (y + 2) = 0
= > y = -2, -2/3
Hence no relation can be established between x and y
