    Directions For Questions

    In the following questions, two equations I and II are given. You have to solve both equations and give answer as,

    a) If x > y

    b) If x ≥ y

    c) If x < y

    d) If x ≤ y

    e) If x = y or the relation cannot be established.

    I) x2 – 31x + 238=0

    II) 2y2 – 26y + 84=0

    Solutions

    x2 – 31x + 238=0

    x2 – 14x – 17x + 238=0

    x(X – 14) – 17(x – 14)=0

    (X – 17)(x – 14)=0

    X=17, 14

    2y2 – 26y + 84=0

    2y2 – 14y – 12y + 84=0

    2y (y – 7) – 12(y – 7)=0

    (2y – 12)(y – 7)=0

    Y=6, 7

    x > y

    I) x2 – 13x – 30=0

    II) y2 – 25y + 150=0

    Solutions

    x2 – 13x – 30=0

    x2 – 15x + 2x – 30=0

    x(x – 15) + 2(x – 15)=0

    (x + 2)(x – 15)=0

    X=-2, 15

    y2 – 25y + 150=0

    y2 – 10y – 15y + 150=0

    y(y – 10)- 15(y – 10)=0

    (y – 15)(y – 10)=0

    Y=15, 10

    Relation cannot be established.
