40 athletes, including 20 people wrestling, fencing and 20 people, 10 people fencing, wrestling would not ask fencing athletes will be wrestling the number of people?

attention because 20 +20 = 40

so every one person will be, it certainly will not be

so a person will be the = are not the = 10

with x people do not it would be

20 +20-10 = 40 - x

x = 10

and this subject as simple as that, you look at the ah: There were 40 athletes, 25 will wrestling, fencing and 20 people, 10 people nothing will, opportunities are wrestling will Fencing 25 +20- (40-10) = 15

at least the same as a 40-10 = 30 people

different city, 20 +20-30 = 10
