Thus, codes for all the numbers remain same. => 236475 = *?â€¢$\div$+$

Ans – (E)

2)Â AnswerÂ (C)

The number 846721 neither starts by an odd number or ends by an even.

Thus, codes for none of the numbers will be changed.

=> 846721 = !$\div$â€¢+*x

3)Â AnswerÂ (A)

The number 178524 starts by an odd number and ends by an even number.

=> 1 will be coded as @

4 will be coded as Â©

=> 178524 = @+!$* Â© 4)Â AnswerÂ (B) The number 25486 ends by an even number. => 6 will be coded as Â© => 25486 = *$ $\div$! Â©

5)Â AnswerÂ (A)

The code for R is %, the code for E is +, the code for N is X and the code for T is $. So, the code for RENT is %+X$.

Option a) is the correct answer.

6)Â AnswerÂ (B)

The word COMPATIBLE is divided into two parts of equal lengths : COMPA & TIBLE

I : COMPA – BQNPD

The diagonally opposite element is substituted by its immediate following alphabet in the English alphabetical series.

=> C is substituted by D at its diagonally opposite position. Similarly, O is substituted by P at its diagonally opposite position and similarly for M, P and A.

II : TIBLE – DKAHS

The diagonally opposite element is substituted by its immediate preceding alphabet in the English alphabetical series.

=> T is substituted by S at its diagonally opposite position. Similarly, I is substituted by H at its diagonally opposite position and similarly for B, L and E.

Following the above method, code for STABILISED is :

STABI – JCBUT

LISED – CDRHK

=> STABILISED – JCBUTCDRHK

7)Â AnswerÂ (C)

In the coded form, the last letter of the original word is the first letter, the first letter of the original word is the second letter in the coded form. The last-but-one letter in the original word is the third letter in the coded form and so on.

So, the code for NUMBERS will be SNRUEMB

8)Â AnswerÂ (D)

The pattern here followed is that the last letter of the word is excluded.

The word RAIL is divided into two parts : RAI & L

I : RAI – KCT

The diagonally opposite element is substituted by its 2nd to the right alphabet in the English alphabetical series.

=> R is substituted by T at its diagonally opposite position. Similarly, A is substituted by C at its diagonally opposite position and I by K.

II : L – N

The last letter i.e. L is substituted by the alphabet second to its right i.e. N

Similar pattern can be observed for SPEAK

Thus, code for AVOID

AVOI – KQXC

D – F

=> AVOID – KQXCF

9)Â AnswerÂ (A)

The letters B, I and T are repeated in both the words. The only letters that are not repeated are R, U , L and E. Hence the code letters that are not repeated in the both the words are selected to get the code for RULE.

10)Â AnswerÂ (D)

The letters are replaced by the next ones in the alphabetical series and then inverted from last to first. Hence, STALE is written as FMBUT.
