This is the correct answer. According to the alphabetical position, code of the word 'HEALTH' is moving on the pattern of +1, +3, +5, +7, +9 and so on. HEALTH = IHFSCS Now, on following the given pattern, we get NEAR = OHFY

The number of letters in the word ROAD is 4. The code is obtained by multiplying 4 with 5, i.e. ROAD = 5 x 4 = 20 Similarly, GUN = 5 x 3 = 15 So, STAR = 5 x 4 = 20

This is the correct answer because the code of word 'HONEY' is moving as +3, -4, +5, -6 and so on according to alphabetical position.

So, HONEY = KKSYF 

Similarly, HAND = KWSX  

This is the correct answer. It is observed that C = square of alphabetical position of letter 'C' = 32 = 9, and READ = sum of squares of alphabetical positions of each letter of the word = 18² + 5² + 1² + 4² = 366 Therefore, FINE = 6² + 9² + 14² + 5² = 338

E = 5, A = 1, T = 20 EAT = 5 x 1 x 20 = 100

R = 18, A = 1, T = 20 RAT= 18 x 1 x 20 = 360

Firstly divide the whole word in two equal parts: ORGA and NISE Reverse the order of letters, right to left of both parts: AGRO and ESIN Now, move +1 position in first part and -1 position in second part.  So, ORGANISE = BHSPDRHM, just like that: DARING = RADGNI = SBEFMH

The code of the word 'DAILY' is moving on a pattern of reversing the letters of word from right to left and moving one step ahead according to alphabetical position. So, DAILY = ZMJBE Similarly, CARDINAL = MBOJESBD

It is given that: 'always create new ideas' = ba ri sha gi, 'ideas and new thoughts' = fa gi ma ri, 'create thoughts and insights' = ma jo ba fa, 'new and better solution' = ki ri to fa, The only word common to the last 3 sentences is 'and' The only common code word is 'fa' Hence, 'fa' stands for' and' Thus, answer option 4 is correct

This is the correct answer. The code of word 'FRIEND' is moving on the pattern +1, +2, +3, +4... letters ahead, according to the English alphabet. So, FRIEND = GTLISJ Similarly, GREAT = HTHEY

This is the correct answer.  

This is the correct answer. According to the alphabetical positions, The starting position of 'S' = 19 and 19 is the ending position of 'H'; The starting position of 'P' = 16 and 16 is the ending position of 'K'; The starting position of 'R' = 18 and 18 is the ending position of 'I' and so on. Therefore, SMILE = HNROV

This is the correct answer. Alphabetical position of 'M' = 13 and sum of digits = 1 + 3 = 4; Alphabetical position of 'E' = 05 and sum of digits = 0 + 5 = 5; Alphabetical position of 'N' = 14 and sum of digits = 1 + 4 = 5; and so on. 

So, MENTION = 4552965 Now, on following the same pattern, we get BROWN = 29655

This is the correct answer as each letter is coded with a letter that is three places preceding it.

C - 3 = Z  R - 3 = O A - 3 = X W - 3 = T L - 3 = I Similarly, F (ED) C R (QP) O A (ZY) X M (LK) J E (DC) B
