✦ Try This: Two salesmen make equal sales during the month of October. In November, each salesman doubles his sales for the month of October. Compare their sales in November. Solve using Euclid’s axiom

Given, two salesmen make equal sales during the month of October.

In November, each salesman doubles his sales for the month of October.

We have to compare their sales in November.

Let the sale of one salesman in October be x.

Given, sales are equal.

So, sale of other salesman in October = x

In November, sale of first salesman = 2x

Sale of second salesman = 2x

Using Euclid’s axiom,

Things which are double of the same thing are equal to one another

Therefore, in November the sales are equal.
