Question

if you multiply me by 2, I become a number greater than 20 and less than 40. if you multiple me by 6 I end in 8

Answer 1

Lets say you are x
20<2x<40
therefore x has to be greater than 10, but less than 20
6x=_8
the only numbers between 10 and 20 that works with this equation are 13 and 18
(6x13=78 and 6x18=108)

Answer 2

2•14=28
28•6=168
Is it 168
