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. P can be represented by 55, 69, etc, and L can be represented by 59, 68, etc. Similarly, you have to identify the set for the word PEST.
Option 1: 87, 56, 03, 04
Option 2: 55, 79, 23, 22
Option 3: 69, 98, 41, 40
Option 4: 96, 65, 32, 00
Correct Answer: 55, 79, 23, 22
Solution :
Given:
PEST
Number representations of each letter –
P→55, 69, 78, 87, 96
E→56, 65, 79, 88, 97
S→00, 14, 23, 32, 41
T→04, 13, 22, 31, 40
Let's check the options –
First option
:
87, 56, 03, 04 – S cannot be represented by 03.
Second option
:
55, 79, 23, 22 – All the letters of the word PEST can be represented through this option.
Third option
:
69, 98, 41, 40 – E cannot be represented as 98.
Fourth option
:
96, 65, 32, 00 – T cannot be represented as 00.
So, only the second option consists of the numbers through which PEST can be represented. Hence, the second option is correct.
