Question 1120930
older daughter is x years now.  Man is 5x, younger daughter is 1/3 x.
In 5 years, man will be 5x+5 and younger daughter 1/3 x+5
so 5x+5=5((1/3 x +5)
5x+5=(5/3)x+25
(10/3)x=20, since 5x=15/3 x
10x=60
x=6 years older daughter
(1/3)x=2 years younger daughter
5x=30 years man.
In 5 years, he will be 35 and younger daughter 7, which is 5 times as much.
