  • Question 1
    1 / -0
    Choose one number which is similar to the numbers in the given set:
    $$992, 733, 845, 632$$
    Solution
    Multiply the 1st and 3rd digits and then add the digits of the number obtained. It will give you the middle digit of the given number:
    1) $$9\times  2 = 18$$
       $$1 + 8 = 9$$ ( middle digit in $$992$$)

    2) $$7 \times 3 = 21$$
        $$2 + 1 = 3$$ (middle digit in $$733$$)

    3) $$8 \times 5 = 40$$
        $$4 + 0 = 4$$ (middle digit in $$845$$)

    4) $$6\times 2 = 12 $$
        $$1 + 2 = 3$$ (middle digit in $$632$$)

    Similarly in $$425$$
    $$4\times 5 = 20$$
    $$0+2 =2$$(middle digit in $$425$$)
    Hence, the similar number is $$425$$.
  • Question 2
    1 / -0
    Pointing to Raman in the photograph, Aditi said, "The only son of his mother is my father." How is Aditi related to Raman ?
    Solution
    Aditi is daughter of Raman.
    Raman's mother's only son (Raman) is father of Aditi.
  • Question 3
    1 / -0
    If in any code language VOYAGE is coded as FIBAPX how is CROWN coded in that language?
    Solution
    Given, VOYAGE is coded as FIBAPX.
    Here, the order of letter 'VOYAGE' is reversed to obtain new word 'EGAYOV'. Now,
    E $$\underrightarrow { +1\quad  } $$ F
    G $$\underrightarrow { +2\quad  } $$ I
    A $$\underrightarrow { +1\quad  } $$ B
    Y $$\underrightarrow { +2\quad  } $$ A
    O $$\underrightarrow { +1\quad  } $$ P
    V $$\underrightarrow { +2\quad  } $$ X
    Similarly, the letter of word CROWN is first reversed to obtain the word NWORC. Now,
    N $$\underrightarrow { +1\quad  } $$ O
    W $$\underrightarrow { +2\quad  } $$ Y
    O $$\underrightarrow { +1\quad  } $$ P
    R $$\underrightarrow { +2\quad  } $$ T
    C $$\underrightarrow { +1\quad  } $$ D
    So, CROWN is coded as OYPTD.
    Hence, option (C) is the correct answer.
  • Question 4
    1 / -0
    In a certain code, PAINTER is written as NCGPRGP, then REASON would be written as
    Solution
    Given, PAINTER is written as NCGPRGP. The coding pattern for the same is:
    P $$\underrightarrow { -2\quad  } $$ N
    A $$\underrightarrow { +2\quad  } $$ C
    I $$\underrightarrow { -2\quad  } $$ G
    N $$\underrightarrow { +2\quad  } $$ P
    T $$\underrightarrow { -2\quad  } $$ R
    E $$\underrightarrow { +2\quad  } $$ G
    R $$\underrightarrow { -2\quad  } $$ P
    Similarly, REASON is coded as follows:
    R $$\underrightarrow { -2\quad  } $$ P
    E $$\underrightarrow { +2\quad  } $$ G
    A $$\underrightarrow { -2\quad  } $$ Y
    S $$\underrightarrow { +2\quad  } $$ U
    O $$\underrightarrow { -2\quad  } $$ M
    N $$\underrightarrow { +2\quad  } $$ P
    Hence, REASON is coded as PGYUMP.
    Therefore, option (C) is the correct answer.
  • Question 5
    1 / -0
    If GOOD is written as HQRH then how will you write DREAM?
    Solution
    Given, GOOD is written as HQRH. The coding pattern for the same is:
    G $$\underrightarrow { +1\quad  } $$ H
    O $$\underrightarrow { +2\quad  } $$ Q
    O $$\underrightarrow { +3\quad  } $$ R
    D $$\underrightarrow { +4\quad  } $$ H
    Similarly, DREAM is coded as follows:
    D $$\underrightarrow { +1\quad  } $$ E
    R $$\underrightarrow { +2\quad  } $$ T
    E $$\underrightarrow { +3\quad  } $$ H
    A $$\underrightarrow { +4\quad  } $$ E
    M $$\underrightarrow { +5\quad  } $$ R
    Hence, DREAM is coded as ETHER.
    Therefore, option (B) is the correct answer.
  • Question 6
    1 / -0
    Rahul told Anand, "Yesterday I defeated the only brother of the daughter of my grandmother." 
    Whom did Rahul defeat?
    Solution
    Rahuls' grandmother's daughter is Rahul's paternal Aunt.
    Her brother is Rahul's father.
    So, Rahul defeated his father.
    option B
  • Question 7
    1 / -0
    If PEARL is written MBXOI then how would DIAMOND be written in that code?
    Solution
    Each letter is coded as the third preceding letter
     $$\displaystyle D\leftarrow A$$
    $$\displaystyle I\leftarrow F$$
    $$\displaystyle A\leftarrow X$$
    $$\displaystyle M\leftarrow J$$
    $$\displaystyle O\leftarrow L$$
    Only AFXJLKA is valid
  • Question 8
    1 / -0
    If TRIANGLE is coded as SSHBMHKF, then SQUARE would be
    Solution
    Given, TRIANGLE is coded as SSHBMHKF. The coding pattern for the same is:
    T $$\underrightarrow { -1\quad  } $$ S
    R $$\underrightarrow { +1\quad  } $$ S
    I $$\underrightarrow { -1\quad  } $$ H
    A $$\underrightarrow { +1\quad  } $$ B
    N $$\underrightarrow { -1\quad  } $$ M
    G $$\underrightarrow { +1\quad  } $$ H
    L $$\underrightarrow { -1\quad  } $$ K
    E $$\underrightarrow { +1\quad  } $$ F
    Similarly, SQUARE is coded as follows:
    S $$\underrightarrow { -1\quad  } $$ R
    Q $$\underrightarrow { +1\quad  } $$ R
    U $$\underrightarrow { -1\quad  } $$ T
    A $$\underrightarrow { +1\quad  } $$ B
    R $$\underrightarrow { -1\quad  } $$ Q
    E $$\underrightarrow { +1\quad  } $$ F
    Hence, SQUARE is coded as RRTBQF.
    Therefore, option (C) is the correct answer.
