Question : Directions: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. D can be represented by 11, 42, etc, and I can be represented by 68, 99, etc. Similarly, you have to identify the set for the word NOSE.
Option 1: 21, 10, 78, 98
Option 2: 13, 22, 66, 56
Option 3: 02, 34, 59, 68
Option 4: 41, 42, 85, 86
Correct Answer: 21, 10, 78, 98
Solution :
Given:
NOSE
Number representations of each letter –
N→02, 14, 21, 33, 40
O→03, 10, 22, 34, 41
S→59, 66, 78, 85, 97
E→55, 67, 79, 86, 98
First option:
21,10, 78, 98; All the letters of the word NOSE can be represented through this option.
Second option:
13, 22, 66, 56; N and E cannot be represented as 13 and 56 respectively.
Third option:
02, 34, 59, 68; E cannot be represented as 68.
Fourth option:
41, 42, 85, 86; N, O cannot be represented as 41 and 42 respectively.
So, NOSE can be represented by using the codes 21,10, 78, 98. Hence, the first option is correct.
