Answer:

12 years later.

Step-by-step explanation:

Let assume in X years, the table will be twice as old as the sofa.

36+X=2(12+X), X=12

Or think it the other way. The difference of ages between two things never change. So they must have a difference(of age) of 24 forever. When will this difference(24) be as same as the younger's age so that the older one is exactly twice as old as the younger? 12 years later when the sofa is 24.

Answer:

<u>Answer: 22 </u>

Here's all the numbers that have 2 or more;

12, 16, 24, 32, 36, 40, 48, 56, 60, 72, 84, 88, 96, 6, 18, 30, 42, 54, 66, 78, 90, 8

Step-by-step explanation:

It seems that 3 and 4 collide ever two steps. (So everytime that happens it has two traits.)

Every time 6 is multiplied it is with 3, so that's a easy one

And 8 is also easy because 4 goes into it too, so 6 and 8 are always have 2 traits.

Forgive me if I missed one, I checked a few times so it should be good!
