Question
Rows of Matrix I are numbered 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 ‘Z’ can be represented by 20, 41, 33 and ‘E’ can be represented by 88, 77, 55. Identify the set for the word PEARL.Solution
P - 00 E - 55 A - 22 R - 11 L - 96
