- Let's define the rates: let $A$ be the rate of one boy from School A, $B$ the rate for School B, and $C$ for School C.

- First statement: 9A + 6B = 1/5 (since they complete it in 5 days).

- Second statement: 5A + 10C = 1/4.

- Third statement: 3B + 4C = 1/10.

- Solve the system of equations to find $A$ .

Using the equations:

- From third statement: 3B + 4C = 1/10.

- From first statement: 9A + 6B = 1/5.

- From second statement: 5A + 10C = 1/4.

After calculations, you'll find:

- One boy from School A (checking math) can do the work in 20 days.

- Therefore, the entire exhibition can be set up by 80 such boys in one day.
