  • Question 1/10
    1 / -0.33

    The following questions is based on the five three-digit numbers given below.

    287 395 678 453 145

    If in each number three digits are arranged in descending order, which of the following will be the lowest?

    Solutions

    As per the given information:

    Given: 287 395 678 453 145

    • If the three digits are arranged in descending order in each number we get:

    Clearly, '145' will be the lowest after the arrangement.

    Hence, the correct answer is "145".

     

  • Question 2/10
    1 / -0.33

    A man pointed to a lady in the photograph and says, "that lady is my son's sister's maternal uncle's only sister." How is the lady in the photograph related to the man?

    Solutions

    By using the symbols in the table given below, we can draw the following family tree:

    According to question

    Lady is the wife of Man.

    Hence, the correct answer is "option (4)".

     

  • Question 3/10
    1 / -0.33

    Island : Sea :: Oasis : ?

    Solutions

    The correct is Desert

    Explanation:

    The relationship between "Island" and "Sea" is one of containment or proximity; an island is typically surrounded by the sea.

    To find a similar relationship for "Oasis," we need to consider what is typically associated with an oasis.

    The analogous term for "Oasis" is "Desert."

     

  • Question 4/10
    1 / -0.33

    How many triangles are there in the given figure?

    Solutions

    The triangles are:

    So, there are '28' triangles in the given figure.

    Hence, the correct answer is "Option 2".

     

  • Question 5/10
    1 / -0.33

    In this question, a statement is followed by two conclusions numbered I and II. You have to assume everything in the statement to be true and decide which of them logically follow(s) beyond a reasonable doubt from the information given in the statement.

    Statement:

    Before leaving for college, Sita is learning to cook basic meals from her mother.

    Conclusions:

    I. Sita didn't know how to cook.

    II. Sita wants to throw a party for her friends before leaving for college.

    Solutions

    Given Statement:

    Before leaving for college, Sita is learning to cook basic meals from her mother.

    Conclusions:

    I. Sita didn't know how to cook. → True (Because Sita is learning to cook basic meals, it implies that she didn't know how to cook)

    II. Sita wants to throw a party for her friends before leaving for college  → False (Nothing mention about 'party for her friends' in the statement) 

    Hence, 'Only conclusion I follows'.

     

  • Question 6/10
    1 / -0.33

    Find the angle between the hour hand and the minute hand of a clock at 6 ∶ 10

    Solutions

    The logic follows here is:

    The angle between the hour hand and the minute hand can be calculated as:

    FORMULA :

    Angle = | (60H - 11M) / 2 |

    Where M = Minutes and H = Hours

    Here, the angle formula is in mod value therefore two angles are calculated from it.

    One is the main angle and another is the reflex angle which can be calculated by subtracting the main angle from 360°.

    Depending on the options we need to choose accordingly.

    Calculation :

    Given time: 6 : 10

    By using the above formula:

    Angle = | (60H - 11M) / 2 |

    Here, H = 6 and M = 10

    Therefore, 

    Angle = | (60 × 6 - 11 × 10) / 2 |

    = | (360 - 110) / 2 |

    = | (250)/2 |

    = | 125 |

    = 125°

    The reflex angle can be calculated as;

    = 360° - 125° = 235°

    Thus,  the angle between the hour hand and the minute hand of a clock at 6 :10 is '125°'.

    Hence, the correct answer is "125°".

     

  • Question 7/10
    1 / -0.33

    Select the correct mirror image of the given figure when the mirror is placed at AB.

    Solutions

    The correct mirror image of the given figure when the mirror is placed at AB is as shown below :

    Hence, the correct answer is "Option 1".

     

  • Question 8/10
    1 / -0.33

    The sum of the ages of father and his son is 60 years. After 15 years, father will be twice as old as his son. Their present ages are :

    Solutions

    Given:

    1) The sum of the ages of father and his son is 60 years.

    2)  After 15 years, the father will be twice as old as his son.

    Calculation:

    Let,

    The present age of Father = x

    The present age of Son = y

    According to the statement,

    x + y = 60

    Therefore, x = 60 - y

    After 15 years,

    Age of Father = x + 15 = 60 - y + 15 = 75 - y .......(1)

    Age of Son = y + 15 ........(2)

    Now, from equations (1) & (2) and according to the statement:

    ⇒ 75 - y = 2(y + 15)

    ⇒ 75 - y = 2y + 30

    ⇒ 3y = 45

    y = 15

    Therefore present age of the son is 15 years.

    The present age of the father is 45 years.

    Hence, the correct answer is "Option (2)".

     

  • Question 9/10
    1 / -0.33

    DIRECTIONS: In question given below, there are two statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with the commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.

    Statements:

    Some engineers are teachers

    Some teachers are efficient

    Conclusions:

    I. Some engineers are efficient

    II. All efficient are engineers

    Solutions

    Statements:

    Some engineers are teachers

    Some teachers are efficient

    The least possible diagram for the given statements is as follows

    Conclusions:

    I. Some engineers are efficient → False (because no direct relationship is given between engineers and efficient so it may be possible but not defined)

    II. All efficient are engineers → False (because no direct relationship given between engineers and efficient so it may be possible but not defined)

    Hence, “If neither conclusion I nor II follows".

     

  • Question 10/10
    1 / -0.33

    The second number in the given number pairs is obtained by performing certain mathematical operations(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair:

    Solutions

    The logic followed here is:

    Logic: First number - 107 = Second number

    1. 444 ∶ 339 → 444 - 107 = 337 ≠ 339
    2. 189 ∶ 82 → 189 - 107 = 82
    3. 401 ∶ 294 → 401 - 107 = 294
    4. 500 ∶ 393 → 500 - 107 = 393

    Hence, '444 ∶ 339' is the correct answer.
