Joe+sister+father=100

=>sister=x
joe+sister=father
therefore, 2*father=100

Joe= 20 Joe's sister = 30 Joe's father = 50

So now, we can add up the three members and can get the sum 100.

now the son is as old as his father , i.e Joe= 50 years

Joe's sister= 60 (twice as old)

case 2

joe = 50 ( as old as father)
sister = 50 (as old as father)
father= 100 (twice as old)

hence father is twice as old as when sister is as old as her father. it would be better if there were options.
