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. X can be represented by 10, 44, etc, and M can be represented by 75, 99, etc. Similarly, you have to identify the set for the word PLAN.
Option 1: 12, 58, 67, 40
Option 2: 41, 76, 98, 04
Option 3: 00, 95, 57, 12
Option 4: 23, 68, 79, 22
Correct Answer: 41, 76, 98, 04
Solution :
Given:
PLAN
Number representations of each letter –
P→00, 12, 23, 34, 41
L→57, 69, 76, 88, 95
A→55, 67, 79, 86, 98
N→04, 11, 22, 33, 40
First option:
12, 58, 67, 40; L cannot be represented as 58.
Second option:
41, 76, 98, 04; All the letters of the word PLAN can be represented through this option.
Third option:
00, 95, 57, 12; A and N cannot be represented as 57 and 12 respectively.
Fourth option:
23, 68, 79, 22; L cannot be represented as 68.
So, PLAN can be represented by using the codes 41, 76, 98, 04. Hence, the second option is correct.
