Direction: In each of these questions, two equations are given. You have to solve these equations and find out the values of x and y and give answer
( 1 ) x < y
( 2 ) x > y
( 3 ) x ≤ y
( 4 ) x ≥ y
( 5 ) x = y

  1. Ⅰ. 16x2 + 20x + 6 = 0
    Ⅱ. 10y2 + 38y + 24 = 0
    1. 1
    2. 2
    3. 3
    4. 4
    5. 5
Correct Option: B

As per the given above equations , we can say that
Ⅰ. 16x2 + 20x + 6 = 0
⇒ 8x2 + 10x + 3 = 0
⇒ (4x + 3)(2x + 1) = 0

∴ x = -
3
or, -
1
4
2
Ⅱ. 5y2 + 38y + 24 = 0
⇒ 5y2 + 19y + 12 = 0
∴ (y + 3)(5y + 4) = 0
∴ y = - 3 or, -
4
5
Hence, required answer will be x > y .
