Question : Directions: In each of the following, questions, 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. E can be represented by 01,12, etc, and L can be represented by 56, 77 etc. Similarly, you have to identify the set for the word given in each question.
AIRS
Option 1: 00, 68, 78, 88
Option 2: 24, 69, 56, 78
Option 3: 43, 55, 86, 95
Option 4: 12, 76, 99, 78
Correct Answer: 43, 55, 86, 95
Solution :
Given:
AIRS
Number representations of each letter –
A→00, 12, 24, 31, 43
I→55, 68, 76, 89, 97
R→57, 65, 78, 86, 99
S→58, 66, 79, 87, 95
First option:
00, 68, 78, 88; S cannot be represented as 88.
Second option:
24, 69, 56, 78; I, R, and S cannot be represented as 69, 56, and 78 respectively.
Third option:
43, 55, 86, 95; All the letters of the word AIRS can be represented through this option.
Fourth option:
12, 76, 99, 78; S cannot be represented as 78.
So, AIRS can be represented by using the codes 43, 55, 86, 95. Hence, the third option is correct.
