Part I : Quantitative Comparison Questions

  1. Since b < 0 , x < 0

        - b - x > 0 and b + x < 0

         \ - b - x > b + x

    Ans : A

  2. Since nothing is stated about l, m, and k, it is impossible to determine the relation.

    Ans : D

  3. If

    Let

    a = 3k; b = 5k

    We get ab = 15k2 and/or ab = 15

    Since the value of k is not known, the relationship cannot be determined.

    Ans : D

  4. m Ð ARB =[Inscribed angle theorem]

        m (arc AXB) = 2 m Ð ARB

         = 220

        m (arc AXB) + m(arc ARB) = 360

           m (arc ARB) = 360 - 220

            = 140

    180 > 140

    i.e. 180 > m (arc ARB)

         Ans : A
