Question

Jack is 3 times as old as Lacy. 8years from now the sum of their ages will be 64. How old are they now?Jack is ? years old while Lacy is ?years old.

Answer 1

Given jack is 3 times as old as lacy.

Let the age of the lacy be x.

Then, the age of the jack is 3x.

After 8 years from now, the sum of their ages will be 64.

`\begin{gathered} (x+3x)+16=64 \\ 4x=64-16 \\ 4x=48 \\ x=(48)/(4) \end{gathered}`

Thus, the value of x will be

`x=12`

Therefore, the age of the lacy is 12 and the age of the jack is

`12*3=36`

Thus, Jack is 36 years old while lacy is 12 years old.
