Below are given 4 encode-decode questions for your practice, to help in solving reasoning questions for bank and other exams.
Question 1
In a certain language the word HOUSEHOLD is coded as SLFHVSLOW then how the word BROADCAST will be coded ?
a) YILWZXZHG
b) YILZWXZHG
c) YZLIWXZHG
d) YILWXZZHG
Answer : b) YILZWXZHG
Reason :
Let us first find the logic used to code HOUSEHOLD. By analysing the code we can infer that, for each alphabets they have assigned a value by reversing the alphabet letters,
i.e. A is assigned the value Z, B - Y, C - X, ....., Z - A.
Now the value of H is S, O - L, U - F, S - H, E - V, H - S, O - L, L - O, D - W.
So HOUSEHOLD is coded as SLFHVSLOW.
Similarly if the same logic is used for BROADCAST, then the code will be YILZWXZHG
Question 2
In a secret code DEGREE is coded as TVWVVI then how TARGET will be coded ?
a) IZGGVT
b) ZIGGVT
c) IZGVGT
d) ZIGVGT
Answer : a) IZGGVT
Reason :
Here the logic used behind the coding is,
First the word DEGREE is splitted into two halves as DEG | REE.
In the next step, the separated words are reversed as GED | EER.
Then the value for each letter is assigned by using the same logic used in the previous question.
i.e. G - T, E - V, D - W, R - I
i.e. TVW | VVI
Next is they have combined the code as TVWVVI.
Thus using this logic TARGET can be coded as IZGGVT
Question 3
There is a MNC company where 1000 of employers are working.Inorder to avoid the message leaking to outsiders they are using a secret code which is known only to senior officers. In that code CHENNAI is coded as 385141419 then find the code for KOLKATA.
a) 111510111201
b) 111015121101
c) 111512111201
d) 111215101211
Answer : c) 111512111201
Reason :
This is a simple question. If you closely analyse the word, you will find that it is an easy question. It may seem to be a logically difficult question by while reading the question, but not if you are careful while gothroughing then it is a time saving question.
Here just the order of each alphabet is used for coding, i.e A - 1, B - 2, C - 3......Z - 26
By applying the value, C - 3, H - 8, E - 5, N - 14, N - 14, A - 1, I - 9.
Thus CHENNAI will be coded as 385141419.
By using the same logic KOLKATA can be coded as 111512111201
Question 4
A group of 5 friends were playing with words.One of the friend said a coded word EDTSSNX and ask others to find the word. One among themselves answered the actual word is DESTROY. Using the same logic,again she posed the other word UZOFMDT then what will be the actual word ?
a) TANGLES
b) CONTACT
c) PROCESS
d) REVENUE
Answer : a) TANGLES
Reason :
By analyzing with the word EDTSSNX, the logic used is -1 and +1 alternatively in the coded word.
If you subtract 1 , i.e the predecessor of the letter E is D.
Next add 1, i.e the successor of the letter D is E.
