Respuesta :

the answer to this question is answer choice C.18

Answer:

C)18

Step-by-step explanation:

Let Sara present age = x years.

According to question Ralph present  age =3x

Sara age after 6 years =x+6.

Ralph age after 6 years =3x+6.

After 6 years Ralph will be only twice as old as Sara will be then.

3x+6=2(x+6)

Solving for x:

3x+6=2x+12

3x-2x=12-6

x=6.

Ralph present age = 3x=3(6)= 18 years.

Option C.
