If IRON is written as GOKI, then KNIFE may be written as

If, 6x4= 12, 4x12= 24, 12x6= 36 then 6x9= ?

If x stands for - , + means x , ÷ means + and - means ÷ , then what is the value of the given expression?

175 - 25 ÷ 5 + 2 x 3 + 10 = ?

If 3 % 2 = 50, 2 % 4 = 60 then what is the value of 5 % 4 = ?

If "S" denotes "multiplied by", "V" denotes "subtracted from", "M" denotes "added to" and "L" denotes "divided by", then

In the 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 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., G can be represented by 04, 40, etc., and 'K' can be represented by 56, 75, etc. 

Similarly you have to identify the set for the word 'NILE'.
