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. I can be represented by 12, 44, etc, and D can be represented by 75, 97, etc. Similarly, you have to identify the set for the word CHEAT.
Option 1: 10, 21, 68, 77, 56
Option 2: 34, 43, 95, 85, 96
Option 3: 41, 14, 76, 99, 79
Option 4: 22, 00, 87, 67, 67
Correct Answer: 41, 14, 76, 99, 79
Solution :
Given:
CHEAT
Number representations of each letter –
C→03, 10, 22, 34, 41
H→00, 14, 21, 32, 43
E→59, 68, 76, 87, 95
A→58, 66, 77, 85, 99
T→55, 67, 79, 86, 98
First option:
10, 21, 68, 77, 56; T cannot be represented as 56.
Second option:
34, 43, 95, 85, 96; T cannot be represented as 98.
Third option:
41, 14, 76, 99, 79; All the letters of the word CHEAT can be represented through this option.
Fourth option:
22, 00, 87, 67, 67; A cannot be represented as 67.
So, CHEAT can be represented by using the codes 41,14, 76, 99, 79. Hence, the third option is correct.
