The respective (sod+pod) of the given array is as follows:
23 27 29
11 47 29
24 21 ?
In this transformed array, C(13)=C(23)=29, it follows:
C(33)=29
Now, the only 2-digit numbers whose (sod+pod) equal 29 are:
29,45,54 and 92
Since 54 and 92 appears at C(13) and C(23) of the given array, it follows that: the numbers appearing in place of interrogation is: 29, or 45
