i think...
the eldest daughter's age must be less than 19..
their ages r 9,4,2 if there r no twins...
or 6, 6, 2 or 3, 3, 12...
since father's age was 20... daughter's age should be less than 19... their ages will be 9,4,2...
if the youger is twins then 12,3,3...
72 can be factorize into
3,3,2,2,2
Also the eldest daughter had just started the piano class. so her age will be 6.
considering this there are 2 possibles. They are
6,6,2 and 6,4,3.
But eldest daughter is 6 yrs old.
So there might not be twins.
Hence the daughters ages are
6,4,3
