Answers & Solutions:
1) Answer (C)
Now, If A is 1, B is 3, C is 5, D is 7, E is 9 and so on…
Going by this logic, we get T as 39
Hence, we can code BEAT as 39139
Therefore, option C is correct option.
2) Answer (B)
We have to analyse each and every expression with the correct symbols,
$70-2+4\div5\times6$ which is actually $70\div2-4\times5+6$
Now, solving $70\div2-4\times5+6$ = 35 – 20+6 = 21
Therefore, the correct option is option B.
3) Answer (C)
The code is obtained by reversing the letters.
Now, reversing the word EXOTIC, we get CITOXE.
Therefore, the code for EXOTIC is CITOXE.
The correct option is option C.
4) Answer (B)
5) Answer (D)
Here, the word is divided into four groups of three letters each.
DIS TRI BUT ION
Each group is used in its reverse manner in new word formed.
Observing the coding of SUBSTITUTION as ITSBUSNOITUT we get,
IRTSIDNOITUB
Therefore, option D is the correct answer.
6) Answer (A)
7) Answer (C)
8) Answer (E)
9) Answer (D)
