Ralph is 3 times as old as sara. in 4 years, ralph will be only twice as old as sara will be then. find ralph's age now.

if x represents sarah's age now, which of the following expressions represents ralph's age in four years?

Step-by-step explanation:

Since, x represents Sarah's present age  then

According to question

Ralph is 3 times as old as Sara.

that is present age of Ralph = 3x

After 4 years age of Sara will be x + 4

and age of Ralph will be 3x + 4.

According to question,

In 4 years, Ralph will be only twice as old as Sara will be then.

⇒ 3x + 4 = 2( x + 4)

Solving for x, we get,

⇒ 3x + 4 = 2 x + 8

⇒ 3x -2x = 8 - 4

⇒ x = 4.

Thus, Sara present is 4 years and Ralph present age is 3x = 12
