### Coding and Decoding Aptitude Question 1: In a certain code, “CODE” is written as “7%#\$” and “BEAR” is written as “2\$@1”. How is “DEAR” written in that code language?

A. %\$@1

B. #\$@1

C. #@\$1

D. %@\$1

E. %1@\$

In this language, the alphabets have been coded as follows: Therefore, DEAR is coded as #\$@1. So, B is the correct option.

### E. None of these

The code has been created using the position number of letters in the English alphabet.

> GARRY

7

1

18  1 + 8 = 9

9

25  2 + 5 = 7

Now we reverse the word and then use the code for each letter.

GARRY → YRRAG → 79917.

> MARE

13  1 + 3 = 4

1

9

5

MARE → 5914

> WIN

23  2 + 3 = 5

9

→ 14 → 1 + 4 = 5

Therefore, WIN is coded as 595. So, C is the correct option.

### E. UXEEVG Similarly, Therefore, the correct option is A.

### E. HLBUME

Leaving the first and the last letter, the order of the position of the remaining letters is reversed. Similarly, “HUMBLE” will be coded as “HLBMUE”. Therefore, D is the correct option.

### E. GOVRENMNET

Leaving the first and the last letter, the position of remaining letters is interchanged in pair of two. Similarly, “GOVERNMENT” will be coded as “GVOREMNNET”. Therefore, A is the correct option.

### E. None of these

Each letter in the word is moved 1 step backward. Similarly, “DISPOSE” will be coded as “CHRONRD”. Therefore, B is the correct option.

### E. VEHUEQO

Reverse the word and then move each letter one step backward. Similarly, “PREVIEW” will be coded as “VDHUDQO”. Therefore, C is the correct option.

### E. SFDHQ

Reverse the word and then move each letter one step backward. Similarly, “TIGER” will be coded as “QDFHS”. Therefore, C is the correct option.

### E. None of these

In this language, the alphabets have been coded as follows: Therefore, MOOD is coded as NOOE. So, C is the correct option.

### E. 541389

The code has been created using the position number of letters in the English alphabet.

> LONDON

12

15

14

4

15

14

Therefore, LONDON → 12151441514

Similarly, DELHI is coded as 451289. So, A is the correct option.
