Small tier = x

Medium tier = y

According to given statement;

1.The situation with a system of equations.

3x+y = 100 Eqn 1

3x+2y=140 Eqn 2

2. Solving the System of equations;

Subtracting\ Eqn\ 1\ from\ Eqn\ 2\\(3x+2y)-(3x+y)=140-100\\3x+2y-3x-y=40\\y=40\\Putting\ value\ of\ y\ in\ Eqn 1;\\3x+40=100\\3x=100-40\\3x=60\\Dividing\ both\ sides\ by\ 3\\\frac{3x}{3}=\frac{60}{3}\\x=20

The solution to the equations is x=20 and y=40
