Question 1079856
 Fathers is three years older than mother
f = m + 3 
 Brother is two years older than sister
b = s + 2
 Their ages added up is 73 
f + m + b + s = 73
 Four years ago their ages added up to 58
(f-4) + (m-4) + (b-4) + (s-4) = 58
f + m + b + s - 16 = 58
f + m + b + s = 58 + 16
f + m + b + s = 74
