 Coding Decoding

11. In a certain code ‘415’ means ‘milk is hot’; ‘18’ means ‘hot soup’; and ‘895’ means ‘soup is brown’. What number will indicate the word ‘brown’?

a) 9

b) 8

c) 5

d) 4

Explanation: The code for ‘hot’ is 1. So, the code of ‘soup’ is 8. Now, the code for ‘is’ is 5. Hence, we can say that the code for ‘brown’ is 9.

12. If CEJQ is coded as XVQJ, then BDIP will be coded as:

a) WURQ

b) YWRK

c) WUPI

d) YWPI

Explanation: The first 13 letters of the alphabet are coded by the 13 letters of the alphabet in reverse, i.e.

= A B C D E F G H I J K L M (first 13 letters)

= Z Y X W V U T S R Q P O N (13 letters in reverse)

It is obvious from the above coding scheme that:

B = Y, D = W, I = R and K = P or P = K

Therefore, B D I P will be coded as Y W R K.

13. If LODES is coded as 46321, how will you code the word DOES?

a) 1234

b) 4321

c) 3621

d) 3261

Explanation: Here, you will observe that all the letters of DOES are included in the letters of LODES, for which you have the code D = 3, O = 6, E = 2, S = 1. Therefore DOES = 3621. So, the answer is (d).
