Let's break this down step-by-step:

* When you were 2 years old, your sister was twice your age

* So if you were 2, your sister was 2 x 2 = 4 years old

Now, you are currently 40 years old. We need to find out how old your sister is now.

To do this, we can use the following equation:

* Sister's current age = Sister's age when you were 2 + (Your current age - 2)

Plugging in the values:

* Sister's current age = 4 + (40 - 2)

* Sister's current age = 4 + 38

* Sister's current age = 42

Therefore, if you are currently 40 years old, and your sister was twice your age when you were 2, then your sister is currently 42 years old.

The math solution is:

* Your age when sister was twice your age: 2 years old

* Sister's age when you were 2: 2 x 2 = 4 years old

* Your current age: 40 years old

* Sister's current age = Sister's age when you were 2 + (Your current age - 2)

* Sister's current age = 4 + (40 - 2) = 4 + 38 = 42 years old
