Question 1

In a certain code language, "apple is sweet fruit" is written as "ka lo mi te", "mango is sweet" is written as "lo mi ra" and "apple mango fresh" is written as "ka ra su". How is "sweet" coded?

Accepted Answer

mi. The common words in the first and second statements are 'is' and 'sweet', and the common codes are 'lo' and 'mi'. In the second and third statements, the common word is 'mango', which matches 'ra'. Therefore, 'sweet' is coded as 'mi'.

Question 2

If "ROAD" is coded as *4@# and "READ" is coded as *7@#, what is the code for "RAOD"?

Accepted Answer

*@4#. From ROAD = *4@#, we get R = *, O = 4, A = @, D = #. The word RAOD is R-A-O-D, so its code is * @ 4 #, i.e. *@4#.

Question 3

If CLOUD is coded as ENQWF, how is RAIN coded?

Accepted Answer

TCKP. In CLOUD → ENQWF, each letter is shifted forward by 2 positions in the alphabet: C→E, L→N, O→Q, U→W, D→F. Applying the same rule to RAIN gives R→T, A→C, I→K, N→P.

Question 4

In the following question, the second word is formed by rearranging the letters of the first word using a specific pattern. Apply the same pattern to the third word. PLANET: LPAENT :: ORANGE: ?

Question 16

If CAT is coded as 24 and DOG is coded as 26, then how is BIRD coded?

Accepted Answer

33. Take alphabet positions: CAT = 3 + 1 + 20 = 24 and DOG = 4 + 15 + 7 = 26. So the code is the sum of letter positions. For BIRD, 2 + 9 + 18 + 4 = 33.

Question 17

If in a certain code, CAT is written as 3 - 1 - 20 and DOG is written as 4 - 15 - 7, then how will PIG be written?

Accepted Answer

16 - 9 - 7. The code replaces each letter with its alphabetical position. CAT becomes 3-1-20, and DOG becomes 4-15-7. Therefore, PIG becomes 16-9-7.

Question 18

In a certain code, PEN is written as 16 - 5 - 14, and BOOK is written as 2 - 15 - 15 - 11. How is NOTE written in the same code?

Accepted Answer

14 - 15 - 20 - 5. The code is based on the alphabetical positions of the letters. N = 14, O = 15, T = 20, and E = 5, so NOTE is written as 14 - 15 - 20 - 5.

Question 19

In the sentence “Still waters run deep”, if each letter is coded using reverse alphabetical order (A→Z, B→Y, …), what will be the code for the 3rd letter of the 1st word?

Accepted Answer

R. The 1st word is “Still” and its 3rd letter is I. In reverse alphabetical coding, A becomes Z, B becomes Y, and so on; therefore I becomes R.

Question 20

If CAT is coded as BZS, how is DOG coded?

Accepted Answer

CNF. In CAT, C becomes B, A becomes Z, and T becomes S. Applying the same rule to DOG gives D→C, O→N, and G→F, so the code is CNF.

Accepted Answer

24, 12, 15, 23. In reverse coding, Z = 1 and A = 26. So C = 24, O = 12, L = 15, and D = 23. Therefore, COLD is coded as 24, 12, 15, 23.

Question 22

If PLANE is coded as 47826 and CAR is coded as 189, how is PLACE coded?

Accepted Answer

47816. From PLANE = 47826, we get P = 4, L = 7, A = 8, N = 2, E = 6. From CAR = 189, we get C = 1 and R = 9, which confirms the mapping. Therefore, PLACE = P L A C E = 4 7 8 1 6 = 47816.

Question 23

If ‘NOTE’ is written as ‘O5@F’ and ‘TONE’ is written as ‘@5OF’, how is ‘EONT’ written?

Accepted Answer

F5O@. From NOTE → O5@F, we get N→O, O→5, T→@, E→F. Applying the same substitutions to EONT gives E→F, O→5, N→O, T→@, so the code is F5O@.

Question 24
