Solution
Let the equal sale of two salesmen in August be x.
In September, each salesman doubles his sales of August.
Thus, sales of first salesmen is 2x and sales of second salesman is 2x.
According to Euclid’s axioms, things which are double of the same things are equal to one another.
So, in September their sales are again equal.
