  • Question 1
    1 / -0
    Three of the four given alternatives are alike in a certain manner. Only one option does not fit-in. Choose the one which is different from the rest.
    Solution
    Except B, the sum of all digits is odd and also, the first digit is 22. Whereas in B sum of digits is even.
    Hence, it is different from others.
  • Question 2
    1 / -0
    In a certain code RITA is written as SJUB. How is CUBA written in that code?
    Solution
    Given, RITA is written as SJUB. The coding pattern for the same is:
    R +1  \underrightarrow { +1\quad  }  S
    +1  \underrightarrow { +1\quad  }  J
    +1  \underrightarrow { +1\quad  }  U
    +1  \underrightarrow { +1\quad  }  B
    Similarly, CUBA is written as follows:
    C +1  \underrightarrow { +1\quad  }  D
    +1  \underrightarrow { +1\quad  }  V
    +1  \underrightarrow { +1\quad  }  C
    +1  \underrightarrow { +1\quad  }  B
    Hence, CUBA is written as DVCB.
    Therefore, option (B) is the correct answer.
  • Question 3
    1 / -0
    In a certain code ROME is coded as SUNI and BOMBAY as CUNCEZ. Then ASIA is coded as ?
    Solution
    The coding pattern is as:
    Except vowel, each of the alphabet is coded by its next alphabet and each of the vowel is substituted by the next vowel.
    So, ASIA is coded as ETOE.
    Hence, option (B) is the correct answer.
  • Question 4
    1 / -0
    In a code language DISTANCE is written as IDTUBECN and DOCUMENT is written as ODDVNTNE. How is THURSDAY written in that language?
    Solution
    The coded pattern is as follows:
    The first two and last three letters of the word are written in the reverse order and each of the remaining letters is moved one step forward to get the code. Thus, we have
    TH/URS/DAY  \longrightarrow  HT/VST/YAD
    Hence, option (D) is the correct answer.
  • Question 5
    1 / -0
    If in a certain language MYSTIFY is coded as NZTUJGZ, how is NEMESIS coded in that language?
    Solution
    Given, MYSTIFY is coded as NZTUJGZ.
    Here, 
    each letter of the word 'MYSTIFY' is moved one step forward to obtain the corresponding letter of the code NZTUJG.
    Similarly, NEMESIS is coded as OFNFTJT.
    Hence, option (B) is the correct answer 
  • Question 6
    1 / -0

    QQ is at the 17th17^{th} place from the start of the alphabet and all three options are on even places. 
    So, option C is the odd one out.
  • Question 8
    1 / -0
    If FACE is coded as GBDF, then BADE will be coded as ________.
    Solution

    So,
    \rightarrow C
    \rightarrow B
    \rightarrow E
    E \rightarrow F
    So, option C.
  • Question 9
    1 / -0
    If in a certain code language ABCD is written as ZYXW, then how is the word DANCE written in that code?
    Solution
    Given, ABCD is written as ZYXW.
    The role of coding is T+n\displaystyle T_{+n} Is coded as Tn\displaystyle T_{-n} 
    'A' is the first letter from the start which is coded as first letter from the end i.e 'Z' and so on.
    Similarly, DANCE is coded as WZMXV
    Hence,option (A) is the correct answer.
