Answer:
C is the answer! B and C are equivalent!
Step-by-step explanation:
The answer is ( C ) or 4/9
Step-by-step explanation:
let father's age be f yr old and son age be s yr old
f = 5s -(1)
f + s = 60 -(2)
sub (1) into (2):
5s + s = 60
6s = 60
s = 10
f = 60 - 10 = 50
in 5 yr time, father age = 50 + 5 = 55
son age = 10 + 5 = 15
