Still the average age of his family is same now. The present age of his wife is     Option 1)   25 years   Option 2)   24 years   Option 3)   32 years   Option 4)   Data insufficient   Option 5)   26 years

The present age of Arthur’s wife is:

$8 years ago => Avg. = 36$

$sum = 36*5 = 180$
$present=> sum = 180 + (5*8) = 220 years$
$After \: baby \: born \: sum = 6*36=216 years$
$But\: we \: can't\: determine \: age\: of \: ifr.$
$So \: Data \: Insufficient.$
