Answer: Present age of Beth is 24 years.
And Present age of Sally becomes 36 years.
Step-by-step explanation:
Let the present age of Beth be 'x'.
Six years ago,
Age of Beth becomes (x-6) years
Age of Sally becomes
[tex]3(x-6)\ yrs[/tex]
Sum of Sally and Beth's age = 60
According to question, it becomes
[tex]x-6+3(x-6)=60+6+6\\\\x-6+3x-18=72\\\\4x-24=72\\\\4x=72+24\\\\4x=96\\\\x=\frac{96}{4}=24\ yrs[/tex]
So, Present age of Beth is 24 years.
And Present age of Sally becomes 60-24=36 years.
