Coding Decoding Type 3 NMAT 2023
In each of the questions given below, a group of letters is given followed by some combinations of number/symbol. You have to find out which of given combination correctly represents the group of letters based on the numbers/symbols codes and the conditions given below. If none of the given combinations represents the group of letters correctly, give (e) i.e. ‘None of these’ as the answer.
Condition for coding the group letters:
(i) If the first letter is vowel and last letter is consonant, the codes for the first and the last letter are to be interchanged.
(ii) If the first as well as the last letter is vowel, then both are to be coded by the code for the last letter.
(iii) If the first as well as the last letter is consonant, then both are to be coded by the code for the first letter.
(iv)If the first letter is consonant and last letter is vowel, the codes for the first and the last letter are to be coded as β.

Frequently asked questions
What is 'Type 3' coding-decoding in NMAT?
This is a condition-based coding type: four rules decide how the first and last letters of a 6-letter group are coded (vowel/consonant combinations), and you apply those rules to find the correct code.
How do I apply the four coding conditions correctly?
Check only the first and last letters of the word for vowel/consonant status first, pick the matching condition (I-IV), then apply it — the middle letters' codes stay unchanged across all conditions.
Are full solutions given for this set?
Yes, each of the 5 questions states which of the four conditions applies (e.g. 'Condition II is applied') as the solution, letting you verify your own working.
How many questions are in this practice set?
Five questions are given, each testing a different one of the four coding conditions on a 6-letter group.
