Some Thoughts re: Hint Comment 2 of 2 |
(In reply to Hint by Ady TZIDON)

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
