Question : Directions: A word is represented by only one set of numbers, as given in any 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 those 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., F can be represented by 24, 41, etc., and P can be represented by 58, 87, etc. Similarly, you have to identify the set for the word UNIT.

I→13, 33
T→57, 65, 68
First option:
22, 78, 34, 69; U, N, I, and T cannot be represented as 22, 78, 34, and 69 respectively.
Second option:
22, 67, 34, 59; U, I, and T cannot be represented as 22, 34, and 59 respectively.
Third option:
14, 69, 24, 75; U, N, I, and T cannot be represented as 14, 69, 24, and 75 respectively.
Fourth option:
85, 67, 13, 57; All the letters of the word UNIT can be represented through this option.
So, UNIT can be represented using the codes 85, 67, 13, 57. Hence, the fourth option is correct.
