Eight years ago, George was half old as Sarah. Sarah is now 20 years older than Geroge. How old will George be 10 years from now?

let geroge's present age be G :
Sarah's present age be S :

Eight years ago, George was half old as Sarah=>

(G-8 )=1/2(S-8 )
2G-S =8......1

Sarah is now 20 years older than Geroge=>

S=G+20.......2

FROM 1 AND 2 .....G= 28

10 Years from now George will be 28+10 = 38 years old ....

Is this the correct answer ..
