Answer 2

Let G be the current age of the girl and M be the current age of the mother.
"A girl is now one-third as old as her mother."
G = 1/3 * M ---- (1)

In three years, the girl will be G+3 years old and mother will be M+3 years old.
" In three years, she will be two-fifths as old as her mother will be."
G+3 = 2/5 * (M+3) ----- (2)

Put G = M/3 from (1) into (2) and solve for M. Then solve for G.
