You can put this solution on YOUR website! There must be a typo, because as it is written it does not make sense.
The ages do not turn out to be whole numbers.
 = current age of the younger girl, and
 = current age of the older girl
"The current age ratio of two girls is 1:3" translates as
 <---> , so
= current age of the younger girl,
 = current age of the older girl,
 = age of the younger girl after 4 years, and
 = age of the older girl after 4 years.
The age ratio of two girls "after four years it will be 2:3" translates as
 <---> <--> <--> ,
and the older girl's age would be  .
Four years later, the older girl's age would be  ,
and the younger girl's age would be 
Although the ratios are as required:
 and  ,
ages are always truncated to whole number,
so  years after being born, a girl's age is said to be  ,
and years after birth, she is said to be  years old.
