Question

Gabriel is 16 years older than sam. in 4 years, gabriel will be twice as old as sam. what is gabriel's age now?

Answer 1

Today In 4 years

Gabriel (G): S + 16 (S + 16) + 4 = S + 20

Sam (S): S (S) + 4 = S + 4

S + 20 = 2(S + 4)

S + 20 = 2S + 8

20 = 2S + 8

12 = 2S

6 = S

Gabriel (G): S + 16 = (6) + 16 = 22

Answer: Gabriel=22 yrs
