Logical Reasoning MCQ - Number and Letter Series

31 ABC, CBA, DEF, ... , GHI, IHG

The second term is the reverse order of the first term. In addition to the above types, a number of other types can also be identified.

32 If ‘A3T15R’ stands for ‘ACTOR’ and ‘D1T5’ stands for ‘DATE’, then how will you code ‘ROTATE’?

While coding ACTOR, first, third and fifth letters have been put without any change. C and O are placed at 3rd and 15th position in alphabetical series. Hence, the code for ACTOR is A3T15R. Similar exercise for DATE. Thus, the code for ROTATE is R15T1T5. Thus, option(a) is the answer.

33 If ‘M I S S I O N’ is coded as ‘ ! ? ? ! φ $’ and ‘LENS’ is coded as ‘@#$?’, then how will you code ‘LION’?

LION = L + ION
Pick L from LENS and ION from MISSION. By careful observation, we can identify that the code for L is @ and the code for ION is !φ $. Hence, option (a) is the answer.

34 In a certain code language, ‘do re me’ means ‘he is late’; ‘fa me la’ means ‘she is early’, and ‘so ti do’ means ‘he leaves soon’. Which word in that language means ‘late’?

do re me − he is late (i)
fa me la − she is early (ii)
so ti do − he leaves soon (iii)
Comparing (i) and (ii), we can say that ‘me’ stands for ‘is’.
Comparing (i) and (iii), we can say that ‘do’ stands for ‘he’.
Substituting them in sentence (i), we can say that ‘re’ stands for ‘late”.
The following arrangement also helps in the solution.
$Coding Decoding$
Hence, the code for ‘late’ is ‘re’.

35 In a certain code, ‘jo ka ra’ means ‘go for walk’; ‘ma fo ka’ means ‘do not walk’, and ‘sa ta jo’ means ‘good for you’. What is the code for ‘go’?

$Coding Decoding$
Hence, the code for ‘go’ is ‘ra’.
