Question: 1 -

In a certain code, PAPER is written as QPARE. How is TABLE written in that code?

Options:
  1. UBAEL

  2. UBALE

  3. UBCMF

  4. UZAKD

  5. Answer:

    UBAEL

    Solution:

    The first letter of the word PAPER is moved one step forward and the next two letters have exchanged their positions and so on. So, following the same coding, T will be coded as U, A will be coded as B, B will be coded as A, L will be coded as E and E will be coded as L. Thus, TABLE is written as UBAEL in that code.


Question: 2 -

In a certain code, TREE is written as UQFD. How is LEAF written in that code?

Options:
  1. MDBE

  2. MFBG

  3. MBZE

  4. KDZE

  5. Answer:

    MDBE

    Solution:

    The letters in the word TREE are moved alternately one step forward and one step backward to form the code UQFD. So, following the same rule, L will be coded as M, E will be coded as D, A will be coded as B, and F will be coded as E. Thus, the code for LEAF is MDBE.


Question: 3 -

In a certain code, ARMY is written as ASOB. How is JUDGE written in that code?

Options:
  1. ITCFD

  2. KVEHF

  3. JVFJI

  4. JWGKJ

  5. Answer:

    JVFJI

    Solution:

    The first letter in the word ARMY remains same and the second, third and fourth letters are moved one, two and three steps forward respectively. Following the same coding, J will be coded as J, U as V, D as F, G as J and E as I. So, the JUDGE is written as JVFJI in that code.


Question: 4 -

If HOT is coded as GNS, How is COLD coded?

Options:
  1. DPME

  2. FROG

  3. BNKC

  4. EQNF

  5. Answer:

    BNKC

    Solution:

    Each letter in the word HOT is moved one step backward to form the code GNS. So, following the same rule, C will be coded as B, O as N, L as K, and D as C. Thus, the code becomes BNKC.


Question: 5 -

If in a certain language, NOIDA is coded as OPJEB, how is DELHI coded in that language?

Options:
  1. IHLED

  2. CDKGH

  3. FGNJK

  4. EFMIJ

  5. Answer:

    EFMIJ

    Solution:

    Each letter in the word NOIDA is moved one step forward to form the code OPJEB. So, in DELHI, D will be coded as E, E as F, L as M, H as I, I as J. Thus, the code becomes EFMIJ.
