Q1- The average age of two persons is 46 years. 16 years back the ratio between their ages were 1 : 2, then what is the difference between present ages of these two persons?

       1) 16 years     2) 20 years     3) 24 years    4) 12 years     5) 8 years

Ans: 2//Let the present age of these two persons are ‘x’ & ‘y’
       (x + y)/2 = 46
        x + y = 92 ...(I)
 now..   x -16/ y-16 = 1/2 =>2x-32= y-16
        =>2x – y = 16 ...(II)
       From equation (I) & (II) x = 36 yrs, y = 56 yrs
       Difference = 56 – 36 = 20

Q2- In how many different ways can the letters of the word “MOBILE” be arranged?

       1) 120      2) 240     3) 360    4) 720    5) 36

Ans: 2// The given number series is based on the following
       pattern :
      12 × 0.5 + 0.5 = 6.5
      6.5 × 1 + 1 = 7.5
      7.5 × 1.5 + 1.5 = 12.75
     12.75 × 2 + 2 = 27.5
     27.5 × 2.5 + 2.5 = 71.25
=> x? = 71.25 × 3 + 3
=> 213.75 + 3 = 216.75

Q7- 16  24  36  54  81  121.5 ?

      

      1) 182.25   2) 174.85   3) 190.65   4) 166.55   5) 158.95

        22 + 12 = 22 + 1 = 23; 23 + 22 = 23 + 4 = 27
        27 + 32 = 27 + 9 = 36; 36 + 42 = 36 + 16 = 52
        52 + 52 = 52 + 25 = 77
        ? = 77 + 62
          = 77 + 36 = 113

Q10- 16 14 24 66 256 1270 ?
