Directions(1-5): Find the relation between x and y and choose a correct option.

  1. I. 3x2 – 25x + 52 = 0
    II. 2y2 – 7y + 3 = 0

    x>=y
    y>x
    x>y
    x=y or relation cannot be established.
    y>=x
    Option C
    I. 3x2 – 25x + 52 = 0
    II. 2y2 – 7y + 3 = 0
    I. 3x2 – 25x + 52 = 0
    => 3x2 – 25x + 52 = 0
    => 3x2 – 12x – 13x + 52 = 0
    => x = 4, 13/3
    II. 2y2 – 7y + 3 = 0
    => 2y2 – 7y + 3 = 0

    C5 + C7 = 1500 * (64.8° + 43.2°)/360°
    = (1500 * 108°)/360°
    = 450
    C2 = 1800 * 28.8°/360°
    = 144
    Required % = 450/144 × l00 = 312.5%

     

  10. The total number of students selected from all seven colleges together in the year 2013 is approximately what per cent of the total number of students selected from all seven colleges in 2012?

    = 1500
    Total (2013) = 270 × 360°/54°
    = 1800
    Required % = 1800/1500 × 100
    = 120%

     

  11. What is the difference between the average number of students selected from Colleges C1, C2 and C3 in the year 2012 and the average number of students selected from Colleges C5, C6 and C7 in the year 2013 ?

    7
    5
    9
    6
    Option D
    Average of C1, C2 and C3
    =(75.6 + 50.4 + 57.6)/(360 * 3) * 1500
