The positional values of the English alphabet is as follows:

The pattern followed here is: Sum of positional values of all the letters - Number of letters in the word

‘ENOUGH’ is written as ‘64’ 

⇒ E(5) + N(14) + O(15) + U(21) + G(7) + H(8) ⇒ 70 - 6 = 64

And,

‘PAIR’ is written as ‘40’

⇒ P(16) + A(1) + I(9) + R(18) ⇒ 44 - 4 = 40

Similarly, 

‘FOCUS’ will be written as:

⇒ F(6) + O(15) + C(3) + U(21) + S(19) ⇒ 64 - 5 = 59

Hence, 'option 3' is the correct answer.

The logic followed here is :-

The alphabetic positional value of consonant is added with +1.

The alphabetic positional value of vowel is subtracted with -1.

CLOUD is written as DMNTE.

And

MANGO is written as NZOHN.

Similarly,

PASTEUR will be written as :

Hence, the correct answer is "QZTUDTS".

The logic follows here is:

Similarly,

From the above diagram, The first and the last letter is A and R

Hence, "A, R" is the correct answer.

The table of alphabet place value:

The pattern followed here is:

• Consonant - are placed there opposite alphabet.
• Vowel - addition of + 5 in vowel.

'LATEX' is written as 'OFGJC'

And,

'RIGHT' is written as 'INTSG'

Similarly,

'SMILE' is written as '?'

Hence, the correct answer is "HNNOJ".

Given: BLANK is coded as KNALB

Similarly,

Hence, TIURF is the correct answer.

The logic followed here is :-

'LEMON' is written as 'ELMNO'.

Similarly,

'CLUSTER' will be written as :

Hence, the correct answer is "CELRSTU".

We know that,

The pattern followed here is as follows,

Similarly,

Thus SWAN is written as 1923114.

Hence, “4” is the last digit of SWAN.

The pattern followed here is:

According to the alphabetical positions of the letters,

Logic is: Sum of the place value of the letters × Number of letters in the word

 SEND = 19 + 5 + 14 + 4 = 42 × 4 = 168

Similarly,

PURSE = 16 + 21 + 18 + 19 + 5 = 79 × 5 = 395 

Hence, ‘395’ is the correct answer.

Logic : Letters of the word are arranged in ascending order according to English alphabetic series.

So,

• 'BEHOLD’ is written as 'BDEHLO'

• 'INDEED' is written as 'DDEEIN'

Similarly,

• 'COURSE' is written as :​

Hence, "CEORSU" is the correct answer.

The table is alphabets place value:

The pattern followed here is:

Step 1: Vowels place values coded as numbers. 

Step 2: Consonants opposite alphabet place value code as numbers.

Step 3: Then this coded number is arranged in reverse order.

‘CROWD’ is coded as 23415924

And,

‘TRHICK’ is coded as 162491997

Similarly,

‘FRUGAL’ be coded

Hence, ‘FRUGAL’ is coded as "1512021921".

The pattern followed here is:

The word is coded as the total letter number of letters present in the word.

6219 means ‘Sachin is a cricketer’

And,

2646 means ‘He played from Mumbai’

Similarly,

‘Mumbai is very famous’ means ?

Hence, the correct answer is "6246".

The position of letters according to the English alphabet series:

Logic: + 3 every letter then arranged alphabetical order.

'CONSULT' is written as 'FOQRVWX'

Similarly,

'MAGNETS' is written as '?'

Hence, the correct answer is "DHJPQVW".

Note:  This is SSC GD Previous year question paper and given answer as per the official answer key.

The letters are replaced by the place value of their reverse letter and then the numbers are added together to obtain the code.

Similarly,

Hence, ‘61’ is the correct answer.

Mistake PointsTOUCH = 20 + 15 + 21 + 3 + 8 =  67 and 67 + 1 = 68

ERROR = 5 + 18 + 18 + 15 + 18 = 74 and  74 + 1 = 75

75 is not in the options so the logic is different here.

The logic here is not sum of positional value + 1, but the logic here is sum of opposite positional value of letters.

The logic followed here is:

 ‘ARROW’ is coded as ‘FOOSE’

‘GERM’ is coded as ‘THOR’

So, by observing the pattern, we can conclude that,

 A = F, R = O, O = S, W = E, G = T, E = H, R = O and M = R.

Now, we have to find the code for MOWER

As the codes of all the letters have been given in the question,

M = R, O = S, W = E, E =H, and R = O

Hence,

‘MOWER’ = ?

Hence, MOWER is coded as ‘RSEHO’.

According to the given information

‘Country’ is coded as 7.

Hence, ‘7’ is the correct answer.
