Six sets (Posted on 2014-02-17) Difficulty: 3 of 5
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?

Any comments?

ok. I have thought that this might be the case, but found it easier

to ask than to add up the quantities to see if the total is 1260.
