Since she has twice as many brothers as sisters, start with 2 and 1...see if that satifies the brother's situation...it doesn't...then try 4 brothers and two sisters...hmmmm, that means her brother has three and three -- we have a winner!

PHYLIS HAS 2 SISTERS & PHIL HAS 3 BROTHERS OR THERE ARE 3 GIRLS & 4 BOYS.
G+O=2*0 NO SOLUTION
G+1 SISTER=2B OK BUT 1B=2 SISTERS NO MATCH
G+2 SISTERS=4B OK & 3B=3 SISTERS A MATCH
