    Split the word into two parts and append the first part at the end of second.

    Correct Option: B

    Split the word into two parts and append the first part at the end of second.

    From question it is clear that we need to make 2 words from word APTITUDE where first word should have first 5 alphabets and remaining 3 alphabets will be part of 2nd word.

    APTITUDE ⇒ APTIT + UDE ⇒ UDEAPTIT

    So the code for APTITUDE is UDEAPTIT.

    Every Alphabet is coded with a particular number.

    Correct Option: C

    From question
    DELHI ⇒ 73541 ---(i)
    CALCUTTA ⇒ 82589662 ...(ii)

    from (i) and (ii)
    C ⇒ 8,
    A ⇒ 2,
    L ⇒ 5,
    I ⇒ 1,
    C ⇒ 8,
    U ⇒ 9,
    T ⇒ 6

    So the code for CALICUT will be 8251896.

    Correct Option: D

    Move +2,+3,+4 forward for first 3 letters
    Move -2,-3,-4 backward for last 3 letters

    C +2 = E
    A + 3 = D

    K - 2 = I
    E - 3 = B
    T - 4 = P

    So The answer is EDWIBP
