CODING DECODING PART 3

GROUP (OR) MIXED CODING :

In this type of questions, three or more sentences are given in the coded language and the code for a particular word is asked. To find the code for the particular word, pickup two sentences bearing a common word and the common code word will mean that word. Proceeding in similar manner, we can be determined a particular code word for each word of given sentences

Example : In a certain code language, po ki top ma' means 'Usha is playing cards"kop ja ki ma' means Asha is playing tennis', ki top sop ho' means they are playing football' and 'po sur kop' means 'cards and tennis, Which word in that language means 'Asha?

1. ja

2. ma

3. kop

4 top

Solution. (a): Comparing relation in each of the statement we get Asha is coded as a

COMBINATION OF LETTERS ,SYMBOLS,NUMBERS CODING :

 In each questions below is given a group of digits followed by four combinations of letters or symbols numbered 1,2,3 and 4. You have to find out which

of the combinations correctly represents the group of digits based on the coding system and the conditions given below and mark the number of that combination as your answer. If none of the combinations correctly represents the group of digits, mark 5, i.e., 'None of these as your answer.

Conditions:

• (i) If the first digit is odd and the last digit is even, the codes for the first and last digits are to be interchanged.

• (ii) If both the first and the last digits are even, both are to be coded as.

•(iii) If both the first and the last digits are odd, both are-to be coded as $.

CODED LETTER OF WORD :

Directions: These questions are based on code language which utilizes letters in the English alphabet. In each question, there is a word written in capital letter, with one letter underlined. For each letter in that word there is a code written in small letters.

is denoted by

1, 2, 3, 4, and 5 not in the same order. You have to find out the

That code exact code for the underlined letter in the word. The number of that code is the answer.

Please note that the same letter appearing in other word(s) may be coded differently

Example 1: QUITE

1. hj

2. su

3. tv

4. pr

5. df

Solution. (2) Each single letter is expressed as two letters, one behind and the other ahead of the given letter Therefore A becomes zb, B comes ac and so on

Example 2: PRISM

1.

R

2.0

3. H

4. Q

5.1

Solution. (4): All

the letters of the word are coded as one letter behind.

Example 3: BEAST
