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?
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?
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?
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?
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?
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.
