The baby's money is 50% of the other two, then the baby's money: (Beibei's money + Zhuang Zhuang's money)=50%:1=1:2

So the baby's money is 60×1/(1+2)=20 yuan, so Beibei's money and Zhuang Zhuang's money is 60-20=40 yuan;

The Beibei's money is one-third of the other two, then the Beibei's money: (Beibei's money + Zhuang Zhuang's money)=1/3:1=1:3

So the Beibei's money: ( Baby's money out + Strong's money out)=1/3:1=1:3

So Bebe's money out is 60×1/(1+3)=15 yuan

So Strong's money out is: 40-15=25 yuan

Answer: Strong's money out is 25 yuan
