Let +a+ = the age of the father
Let +b+ = the age of the younger daughter
+30+ = the age of the elder sister
--------------------------------------------
(1) +a+=+2b+
(2) +b+=+30+-+5+
-----------------------
(2) +b+=+25+
(1) +a+=+2%2A25+
(1) +a+=+50+
-----------------------
The father is 50
The younger daughter is 25

The older sister is 30 years old.                           <<<---=== GIVEN !


Hence, the younger sister is 30-5 = 25 years old.           <<<---=== From the condition.


It implies that the age of the father is 2*25 = 50 years.   <<<---=== From the condition.

Solved.
