Notice that (999)(9999) is an integer multiple of 999
ALSO, (999)(9999) is an integer multiple of 9999
So, sets S and T have this value in common.
Now notice that (2)(999)(9999) is an integer multiple of 999, AND it's an integer multiple of 9999. So, sets S and T have this value in common.
Also, (3)(999)(9999) is an integer multiple of 999, AND it's an integer multiple of 9999. So, sets S and T have this value in common.
And (4)(999)(9999) is an integer multiple of 999, AND it's an integer multiple of 9999. So, sets S and T have this value in common.
As you can see, we can continue this line of reasoning FOREVER.
So, we get:
Quantity A: INFINITY
Quantity B: 9
Answer:
Show: ::
A
