 Six sets (Posted on 2014-02-17)
Please scrutinize the following sets of integers:

S1 (2, 5, 8)
S2 (22, 55, 888, 201)
S3 (232, 88781, 20)
S4 (1, 635, 5, 868, 781, 20 ,115)
S5 (26, 3 ,19, 110, 35, 544, 82, 68, 781, 207)
S6 (3 ,14, 15, 926, 535)

I am choosing one random member from each set :
e.g. 2, 888, 20, 1, 544 and 926.

Sum of those numbers apparently ends by 1.

How many distinct results generated this way will terminate by 1?

How many by a zero digit?

Your result are correct, the conclusions as to WHY it happened - not quite.

Actually it is a D1  puzzle, but branding it  a priori as "easy, almost self-evident" would be counter-productive.

Once you scrutinize the members of  S5 you will immediately understand how the number 1260 is derived and why the counting of "ways" is immaterial.<o:p> </o:p>
