Question
Solve the following question using appropriate Euclid’s axiom: Two salesmen make equal sales during the month of August. In September, each salesman doubles his sale of the month of August. Compare their sales in September.
✓
Answer
Let the sales of two salesmen in the month of August be $x$ and $y$. As, they make equal sale during the month of August, $x = y.$ In September, each salesman double his sale of the month of August, So $2x = 2y$. Now, by Euclid’s axiom, thing which are double of the same things are equal to one another. Hence, we can say that in the month of September also, two salesmen make equal sales.
