Hey <Strawberry>,

Email was sent to you to reconfirm the tabulation in your question (which may not appear precise). Would like to confirm the following points:

Row 1 numbers ( 9, 6, 3 ) start from A
Row 2 numbers ( 12, 15 ,18 ) start from B
Row 3 numbers ( 27, 24, 21 ) start from A
Row 4 numbers ( 30, 33, 36 ) start from B


If this is the actual tabulation , then the answer is in column C

=======

Your clarification is much appreciated.

Cheers,
Edward

Hey <Strawberry>

Following is my worked solution :

*** - for alignment purpose


Col ****** A *B *C **D

Row 1 ****** 9 **6 **3
Row 2 ** 12 15 18 ***
Row 3 ****** 27 24 *21
Row 4 ** 30 33 36 ***

Col A
Multiple of 2,
Multiple of 3,
Multiple of 6,
[(Multiple of 18) + 12]

Col B
Multiple of 3,
[(Multiple of 6) + 3]

Col C
Multiple of 3
Multiple of 6

Col D
Multiple of 3
[(Multiple of 2) + 1]
[(Multiple of 18) + 3]


1995 is found in Column (Col) B as it does not meet the conditions in Col A, C and D.

=========

Trust this helps.

Do let me know again if this is different from your <Answerkey> or if there's further clarification.

Cheers,
Edward
