Question 629721
Jake will use the club 180 times
Snake will use the club 120 times
-------------------------
I don't want to count twice those days
when both use the club, only once.
--------------------------
The 1st day gets counted only once, 
so I subtract 1
--------------------------
Since 6 is the smallest number that
is divisible by both 2 and 3,
every day 6 is a day when both
are there, so {{{ 360/6 = 60 }}}
and I subtract 60
--------------------------
{{{ 1 + 60 = 61 }}}
{{{ 360 - 61 = 299 }}}
So, 299 days total out of 360 at least one of them use the club
Hope I got it
