Solution

The correct option is C $6$
P $= 4$
Difference between P and T $= 5$
Hence, T is assigned $= 9$
Difference between N and T $= 3$
Hence, N is assigned $= 6$

Hence, option C.

Q. 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

4

and that of Matrix

I

are numbered from

5

9

. A letter from these matrices can be represented first by its row and next by its column, e.g.

^{'} A^{'}

can be represented by

00, 12, 23

^{'} P^{'}

can be represented by

58, 69, 75

etc. Similarly, you have to identify the set for the word 'POET'.
