Free Practice Questions for Coding-decoding-test in Reasoning

Similarly,

Hence, option (1) is the correct answer.

The last letter of the place value is written.

Alphabets are coded as -  A = 26, B = 25, C = 24……………..Z = 1

As,

MACHINE =  M(14) A(26) C(24) H(19) I(18) N(13) E(22)

= M(1+4) A(2+6) C(2+4) H(1+9) I(1+8) N(1+3) E(2+2)

= M(5) A(8) C(6) H(10) I(9) N(4) E(4)

= 5861944

Similarly,

STORK = S(8) T(7) O(12) R(9) K(16)

= S(8) T(7) O(1+2) R(9) K(1+6)

= S(8) T(7) O(3) R(9) K(7)

= 87397

Therefore, option (3) is the correct answer.

The logic follows here is:

and

Similarly,

Hence, "CQGYJD" is the correct answer.

Here the following pattern is followed;

 for consonants the place value of the letter is the coded number whereas, for vowels the place value of the opposite letter is the coded number as shown below:

Therefore,

Hence, option (2) is the correct answer.

Here the following logic is followed;

The coded number is the square of the digit obtained by just counting the number of letters in the respective word for example:
FOSTER – 6 letters
The square of 6 = 36
Thus,
DANCE – 5 letters
The square of 5 = 25
Therefore,
ORCHARD – 7 letters
The square of 7 = 49
Hence, option (3) is the correct answer.

 logic →  Here we add 7 to each letter of the word to get a new word;

Similarly,

Hence, option (4) is the correct answer.

 Here the following logic is followed;

Hence, option (1) is the correct answer.

Add place value of first and last letter of PRICK $=16+11=27$
Similarly MAKE $=M+E=13+5=18$
Similarly CRAZY $=C+Y=3+25=28$
Hence, option 1 is the correct answer.

PLEASANT is written as BFMQOBT.
Write PLEASANT in two parts PLEA and SANT.
Write PLEA and SANT in reversing order - AELP and TNAS.

Similarly break DISTANCE in two parts and write in reverse order i.e., TSID an ECNA.

So DISTANCE is written as UTJEFDOB.

Hence, option 3 is the correct answer.

The letters of the given word 'GROUP' is coded with opposite letters in English Alphabet. Similarly, 'RATIO' will be coded as 'IZGRL'.

Hence, option (2) is correct answer.

Below here the following logic is followed;

The coded number of first three letter is the place value of the opposite letter of the respective letter, and the coded number of the last three letters is the place value of that letter.

Similarly,

Therefore;

Hence, option (3) is the correct answer.

Below here this logic is followed;

the coded number is the exact place value of the respective letter as per Alphabetical series.

Similarly,

Hence, option (3) is the correct answer.

Here the following logic is followed;

 The coded letter is the opposite letter of the respective letter as per Alphabetical order.

Similarly,

Hence, option (4) is the correct answer.

Here the following pattern is followed;

Similarly,

Hence, option (4) is the correct answer.
