Coding Decoding 1
This type of reasoning problems tests your ability to decipher the rule that codes a word or message and to code the given word or message following the same rule.
1) If in a certain language, NOIDA is coded as OPJEB, how is DELHI coded in that language?
- CDKGH
- EFMIJ
- FGNJK
- IHLED
Answer: B
Explanation:
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.
2) If HOT is coded as GNS, How is COLD coded?
- BNKC
- DPME
- EQNF
- FROG
Answer: A
Explanation:
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.
3) In a certain code, TREE is written as UQFD. How is LEAF written in that code?
- MFBG
- KDZE
- MDBE
- MBZE
Answer: C
Explanation:
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.
4) In a certain code, PAPER is written as QPARE. How is TABLE written in that code?
- UBALE
- UBCMF
- UZAKD
- UBAEL
Answer: D
Explanation:
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.
5) In a certain code, ARMY is written as ASOB. How is JUDGE written in that code?
- KVEHF
- JVFJI
- ITCFD
- JWGKJ
Answer: B
Explanation:
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.
