Question

In 20 years, Cathy will be five times older than she is today. What is
her current age? With full explanation.

Answer 1

Answer:

5 years

Step-by-step explanation:

Let the current age of Cathy be x years.

Age after 20 years = x+20

But after 20 years, he will be fives times older than she is today.

Therefore, x+20 = 5x

or 5x - x = 20

or 4x = 20

or x = 20/4

or x = 5 years

Answer 2

Answer:

5 years

Step-by-step explanation:

After 20 years ratio will be 1:5

since it is mentioned that she is 5 times older than today, we can write it as 1:5.

now the answer :

1:5=1/5

20/1*1/5

1/4

last step- 20/1*1/4

=5

therefore answer 5 years.
