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. K can be represented by 10, 41, etc, and N can be represented by 56, 97, etc. Similarly, you have to identify the set for the word TREND.
Option 1: 14, 13, 12, 65, 76
Option 2: 43, 42, 40, 78, 88
Option 3: 21, 34, 24, 57, 95
Option 4: 30, 01, 3, 97, 59
Correct Answer: 43, 42, 40, 78, 88
Solution :
Given:
TREND
Number representations of each letter –
T→02, 14, 21, 30, 43
R→01, 13, 20, 34, 42
E→03, 12, 24, 31, 40
N→56, 65, 78, 89, 97
D→57, 69, 75, 88, 96
First option:
14, 13, 12, 65, 76; D cannot be represented by 76.
Second option:
43, 42, 40, 78, 88; All the letters of the word TREND can be represented through this option.
Third option:
21, 34, 24, 57, 95; N and D cannot be represented by 57 and 95 respectively.
Fourth option:
30, 01, 03, 97, 59; D cannot be represented by 59.
So, TREND can be represented by using the codes 43, 42, 40, 78, 88. Hence, the second option is correct.
