Grid and Matrices Easy Questions and Answers

Direction: In the following question, 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 2 matrices given below. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II from 5 to 9. A letter from these matrices can be represented first by its row and next by column number. For example, ‘W’ can be represented by 13, 20 etc. ‘H’ can be represented by 66, 78 etc. Identify the set for the word PENS.

From above given matrices I and II , we get different values for all given letters in matrices -
P ⇒ 00, 12, 24, 31, 43
E ⇒ 56, 68, 75, 87, 99
N ⇒ 02, 14, 21, 33, 40
S ⇒ 04, 11, 23, 30, 42

Correct Option: C

From above given matrices I and II , we get different values for all given letters in matrices -
P ⇒ 00, 12, 24, 31, 43
E ⇒ 56, 68, 75, 87, 99

From given matrix it is clear that all the values for word PENS are matched in only option ( 3 ) for every letter . So , the set for the word PENS will be 43, 56, 21, 42 .From matrix , option ( 3 ) is required answer.

Direction: In each of the following questions, 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 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. ‘E’ can be represented by 01, 13, etc. and ‘L’ can be represented by 56, 77 etc. Similarly, you have to identify the set for the word given in each question.

Direction: In the following two questions, given below are the two matrices each containing two classes of letters from the alphabets. The columns and rows of Matrix I are prime numbered and that of Matrix II are composite numbered. Letter from these matrices can be represented first by its row number and next by its column number. e.g. P can be written as 48, 66, 84 etc. In the following questions identify one set of number pairs out of (1), (2), (3) and (4) which represent the given word.
