DIRECTIONS for the question 1 to 3: Go through all the options and mark the one which does not belong to the group.
    1. 71-55
    2. 517-523
    3. 248-231
    4. 547-563

    Answer: Option C
    248-231 = 17
    563-547=16
    71-55=16
    523-517=06
    Except in the number pair 248-231, in all others number pair, the difference between the two numbers is an even number.
  1. 10, 13, 234, 681, 997
    1. 681
    2. 13
    3. 234
    4. 10

    Answer: Option A
    10⇒ 1+0 =1 or 1^2
    13⇒ 1+3 = 4 or 2^2
    234 ⇒ 2+3+4 = 9 or 3^2
    681 ⇒ 6+8+1 = [15]
    997 ⇒ 9+9+7 = 25 or 5^2
    So the sum of the digits in all the numbers is a perfect square except for 681, hence that is odd.
  2. Choose amongst the Options below.
    1. Heed
    2. Led
    3. Heap
    4. Head

    Answer: Option B
    Except in the word Led, in all other words there are two vowels.
    Hence the answer is option B.
DIRECTIONS for the question 4-8: What should come in place of question mark (?) in the following number/alphabetic series
  1. C – 3, E – 5, G – 7, I – 9, ?, ?
    1. K – 11, M – 13
    2. O – 15, X – 24
    3. M – 18, K – 14
    4. X – 24, M – 21

    Answer: Option A
    Bullseye BigBull
  2. 5, 16, 51, 158, ?
    1. 483
    2. 481
    3. 1454
    4. 1452

    Answer: Option B
    5 × 3 + 1 = 16
    16 × 3 + 3 = 51
    51 × 3 + 5 = 158
    158 × 3 + 7 = [481]
  1. 9 × 2: 9 × 9 : : 9 × 5 : ?
    1. 9 × 6
    2. 9 × 7
    3. 9 × 8
    4. 9 × 4

    Answer: Option A
    9×2=18
    9×9=81
    The digits of resultant have interchanged positions therefore,
    9×5=45
    9×6=54
  2. AFI, JOR, MRU, ?
    1. HMP
    2. PMO
    3. RJL
    4. GJN

    Answer: Option A
    Bullseye BigBull
  3. bc, cde, de, efg, fg, ?
    1. fgh
    2. hij
    3. ijk
    4. Gh

    Answer: Option D
    The answer should be the last alphabhet of fg ( i.e g ) and the next two alphabets i.e hi . Hence answer is ghi
    bc → cde → de → efg → fg → ghi
  4. A man showed a boy next to him and said – “He is the son of my wife’s sister-in-law, but I am the only child of my parents.” How is man's son related to him?
    1. Brother

    4. Cousin

    Answer: Option D
    The boy is the son of man’s brother-in-law. Therefore, man’s son is the cousin of that boy.
  5. Find the correct group of signs to solve the equation. 24 * 16 * 8 * 32
    1. - + =
    2. x / =
    3. + - =
    4. / - =

    Answer: Option C
    The best way to solve this question is by hit and trial . Use the answer options and find the value.
    24 * 16 * 8 * 32
    ⇒ 24 + 16 - 8 = 32
    ⇒ 40-8 = 32
    In this case, option C is correct.
