What should be the value of x,y, and z?
Don't forget to explain the rule.
The values are
X= ABC and Z = BBC , as in each row, column and both the diagonals the counts of A, B, C is 3.
So it follows that
Y = AA
Z= CBB , Y = AA, X = ABC
If we take all the alphabets individually, (a,b,c) are occurring thrice in every row and column respectively with a total of 9 alphabets in each row and column.
The order of the alphabets in z is correct because of the pattern in row1, row3 and row4 ( single alphabets is with two same alphabets, a is with bb and cc with a leading once (ABB) and a at the end other time (CCA) )
