A total of 680 adults visited the swimming pool yesterday, among whom there were 30% fewer men than women. How many men visited the swimming pool yesterday?

Correct answer:

m =  280

Step-by-step explanation:

r=30%=10030=103=0.3 m+z=680 m=zz r=z(1r)  m+m/(1r)=680 m+m/(10.3)=680  2.428571m=680  m=2.42857143680=280  m=280   Verifying Solution:   z=m/(1r)=280/(10.3)=400 d=z+m=400+280=680
