Answers
Question 1:
★ Sample word - TRAIN
★ Sample word in códed language - WUDLQ
In order to find how to códe the question word, we first have to find the pattern in which the sample word was códed.
Let's do it it step-by-step taking each letter.
The first letter in the sample word is 'T' and in the códe, it is 'W'.
➡ T (+2) --- W (Two letters succeeding the actual letter)
Continuing and finding through the same process:
➡ R (+2) --- U (Two letters succeeding the actual letter)
➡ A (+2) --- D
➡ I (+2) --- L
➡ N (+2) --- Q
The given pattern is constant. Hence the pattern which is used to códe the sample word is:
"In the códe language, the alphabet used will be the two letters succeeding the actual alphabet in the word."
Applying the same pattern to the question word:
★ Question Word - BUS
➡ B (+2) --- E
➡ U (+2) --- X
➡ S (+2) --- V
Therefore BUS will be códed into EXV.
The required correct option is:
Option B: EXV ✔
Question 2:
★ Sample word - UNITED
★ Sample word in códed language - SLGRCB
In order to find how to códe the question word, we first have to find the pattern in which the sample word was códed.
The first letter in the sample word is U and in the códed language is S.
➡ U (-1) --- S (One letter preceding the actual letter)
Decóding in the same way:
➡ N (-1) --- L
➡ I (-1) --- G
➡ T (-1) --- R
➡ E (-1) --- C
➡ D (-1) --- B
The given pattern is constant. Hence the pattern which is used to códe the sample word is:
"In the códe language, the alphabet used is one letter preceding the actual alphabet in the word."
Applying the same pattern to the question word:
★ Question Word - DISOWN
➡ D (-1) --- B
➡ I (-1) --- G
➡ S (-1) --- Q
➡ O (-1) --- M
➡ W (-1) --- U
➡ N (-1) --- L
Therefore DISOWN will be códed into BGQMUL.
The required correct option is:
Option A: BGQMUL ✔
Step-by-step explanation:
T¹ W, R ¹ U, A ¹ D, I ¾L, N¹Q ⇒B¹E, U¹X, SV.
