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. T can be represented by 03, 31, etc and D can be represented by 75, 87, etc. Similarly, you have to identify the set for the word GHOST.
Option 1: 33, 57, 20, 66, 03
Option 2: 40, 78, 42, 97, 10
Option 3: 12, 96, 13, 77, 30
Option 4: 04, 78, 01, 58, 43
Correct Answer: 33, 57, 20, 66, 03
Solution :
Given:
GHOST
Number representations of each letter –
G→04, 12, 21, 33, 40
H→57, 69, 78, 85, 96
O→01, 13, 20, 34, 42
S→58, 66, 77, 89, 95
T→03, 10, 22, 31, 44
First option:
33, 57, 20, 66, 03 – All the letters of the word GHOST can be represented through this option.
Second option:
40, 78, 42, 97, 10 – S cannot be represented by 97.
Third option:
12, 96, 13, 77, 30 – T cannot be represented by 30.
Fourth option:
04, 78, 01, 58, 43 – T cannot be represented by 43.
So, only the first option consists of the numbers through which GHOST can be represented. Hence, the first option is correct.
