    I. 225x ²-31=33
    225x ²=64


    II.



    So, X ≤ Y
  • Question 4/10
    1 / -0.25

    Directions For Questions

    Direction: In the following question, two equations (I) and (II) are given. You have to solve both the equations and find out the relationship in between variables:

    I. 3x² +13x +14 = 0
    II. 3y²+11y+10 = 0
    Solutions
    I. 3x² +13x +14 = 0
    => (3x+7) (x+2)
    => x = -7/3, -2
    II. 3y²+11y+10 = 0
    => (y+2) (3y+5)
    => y = -2 , -5/3
    So x ≤ y

    I.x3 – 120 = 5
    II. y2 – 9 = 0
    Solutions
    I. X3 = 125
    X= +5 
    II. Y2=9
    Y=
    Clearly, X>Y.
  • Question 6/10
    1 / -0.25

    Directions For Questions

    Direction: Study the following information and answer the questions given below.
    8 persons M, N, O, P, Q, R, S and T are sitting in a straight line facing North. They have different ages – 10, 13, 15, 18, 25, 26, 31 and 40 but not necessarily in the same order.There are 2 persons sitting between P and the one whose age is 18 years. Neither of them is sitting at an extreme end. The difference between the ages of N and O is 3 years. S is sitting second to the right of the one whose age is 18 years. R is sitting third to the left of the one whose age is 31 years. There are three persons sitting between N and the one whose age is 18 years old. R and O are immediate neighbours. S is not 31 years old. There are at least 4 persons sitting to the right of N. Q and the one whose age is 18 years are immediate neighbours. The one who is 31 years old is not sitting at the second position from any end. M is 3 years older than P. T is one year older than S and are sitting adjacent to each other.

    Who is 13 years old?
    Solutions
    Here we have to cases possible-
    Case1.

    Case2-

    But N will have to be at extreme left position, so that he will have at least 4 persons on their right.
    So case 2nd is wrong.
    R and O are immediate neighbors. And R is sitting 3rd to left of persons whose age is 31 years.
    Difference between age of N and O is 3.
