Mary will be 24 years old when she will be twice as old as
her brother.
Here's how this has been calculated:
If Mary is 16 years old and 4 times older than her brother,
her brother's age
= 16/4
=4
Mary’s brother is therefore 4 years old.
Now let’s calculate the difference between Mary and her
brother’s age through subtraction:
Mary’s age- her brother’s age= 16-4
=12
Therefore, Mary is 12 years older than her brother
So, for Mary to be twice as old as her brother, the formula
will be= 12*2
=24
Therefore, Mary will be 24 years old when she will be twice as old as
her brother.
