  • Question 1/10
    1 / -0.25

    Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out.

    Solutions

    The logic behind the given letter-clusters is:

    BDGJ – B (+2) D (+3) G (+3) J ... (odd one)

    DGJM – D (+3) G (+3) J (+3) M

    KNQT – K (+3) N (+3) Q (+3) T

    TWZC – T (+3) W (+3) Z (+3) C

    Hence, the correct answer is BDGJ.

     

  • Question 2/10
    1 / -0.25

    In the following question, select the related number group from the given alternatives.

    459 : 5 :: 882 : ?

    Solutions

    The logic is:

    459 = 45 ÷ 9 = 5

    Similarly,

    882 = 88 ÷ 2 = 44

    Hence, the correct answer is 44.

     

  • Question 3/10
    1 / -0.25

    A person travels 6 km to east, then 4 km towards north, then again 3 km to east, then 5 km towards south-west. How far he may be from his starting point?

    Solutions

    As per the information given in the question:

    From the figure, we can see that he is 6 km from the starting point.

    Hence, the correct answer is 6 km.

     

  • Question 4/10
    1 / -0.25

    In a row of 20 persons, Meena sits at 9th position from the right end and Kumkum sits at 16th position from left end. How many persons sits between Meena and Kumkum?

    Solutions

    Number of persons - 20

    Kumkum's position from left - 16th

    Meena's position from right - 9th

    Meena's position from left - (20-9+1) = 12

    Number of persons between Meena and Kumkum = (16 - 12 - 1) = 3

    Hence, the correct answer is 3.

     

  • Question 5/10
    1 / -0.25

    Select the number that can replace the question mark (?) in the following series.

    2, 10, 26, 50, 82, ?

    Solutions

    The pattern is:

    Hence, the correct answer is 122.

     

  • Question 6/10
    1 / -0.25

    Which answer figure will complete the pattern in the question figure?

    Solutions

    After carefully observing the figures given in the question, it is very clear that the answer in figure(A) will be the missing figure.

     

  • Question 7/10
    1 / -0.25

    Select the number that can replace the question mark (?).

    C10G, H20L, L17E, L(?)Q

    Solutions

    Here the pattern is: sum of the place value of letters

    C(3) + G(7) → 3 + 7 = 10

    H(8) + L(12) → 8 + 12 = 20

    L(12) + E(5) → 12 + 5 = 17

    L(12) + Q(17) → 12 + 17 = 29

    Hence, the correct answer is 29.

     

  • Question 8/10
    1 / -0.25

    Identify the diagram that best represents the relationship among the given classes.

    Rat, Shoes, Bat

    Solutions

    Here Rat, Shoes, and Bat are three different from each other.

    So the best representation is-

     

  • Question 9/10
    1 / -0.25

    Two statements are given, followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seen to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.

    Statements:

    Some octopuses are fish.

    Some fish are frogs.

    Conclusions:

    I. Some frogs are fish.

    II. Some fish are octopuses.

    Solutions

    Minimum Possible diagram is-

    Conclusions:

    I. Some frogs are fish. (it follows because Some fish are frogs.)

    II. Some fish are octopuses. (it follows because Some octopuses are fish.)

    So, both conclusions follow.

     

  • Question 10/10
    1 / -0.25

    Select the letter-cluster that can replace the question mark (?) in the following series.

    DFH, FHJ, ? , JLN, LNP

    Solutions

    The pattern is:

    Hence, the correct answer is HJL.
