john is three times as old as Greg, and Greg is half the age of Bob, Steve is two times the age of John and Bob combined. if Steve's age is 60, how old is Greg's older cousin Jane, who is two years older than Greg?

Answer 1

j = 3g
g = b/2
s = 2(j+b)
s = 60

solving those, we get Greg is 6.
So, Jane is 8.
