Answers & Solutions:

1) Answer (D)

In the given code language, 

D = #, L = ^, T = %, E = @, G = !, R = ?, A = *, M = &.

Therefore, the code for TELEGRAM is coded as %@^@!?*&.

Hence, option d is the correct answer.

2) Answer (B)

The codes for each letter is given :

R -> 7
U -> 5
B -> 8
B -> 8
E -> 9
R -> 7

Thus, RUBBER : 758897

=> Ans – (B)

3) Answer (B)

Expression : 14641 Q 121 P 100 S 2 R 100 =?

$\equiv14641\div121-100\times2+100$

= $(\frac{14641}{121})-(100\times2)+(100)$

= $121-200+100=21$

=> Ans – (B)

4) Answer (C)

“MATERIAL” is written as “RIALMATE”

The pattern followed is that the word is divided into two parts = (MATE) (RIAL) and both of them replace each other, i.e. = (RIAL) (MATE) to form the code.

Similarly, for REMEMBER = (REME) (MBER), swapping both parts, we get :

REMEMBER : MBERREME

=> Ans – (C)

5) Answer (C)

“CERTAIN” is written as “DFSTBJO”

The pattern followed is :

Similarly, for CRICKET : DSJCLFU

=> Ans – (C)

6) Answer (C)

Expression : 87 B 3 C 4 A 4 D 50 = ?

$\equiv87\div3\times4+4-50$

= $(29\times4)-46$

= $116-46=70$

=> Ans – (C)

7) Answer (C)

“TERMITE” is written as “UDSLJSF”

The pattern followed is :

Similarly, for MINISTER : NHOHTSFQ

=> Ans – (C)

8) Answer (C)

The codes for each letter is given :

R -> 7
A -> 4
G -> 2
E -> 3

Thus, RAGE : 7423

=> Ans – (C)

9) Answer (D)

Expression : 12 V 3 M 441 L 21 S 8 = ?

$\equiv12-3+441\div21\times8$

= $9+(21\times8)$

= $9+168=177$

=> Ans – (D)

10) Answer (B)

“MOTHER” is written as “NPUGDQ”

The pattern followed is :

Similarly, for ORANGE :

=> Ans – (B)
