Answer 1

Answer:

The number of balls sold by Sonu on day 1,

were equal to the profit on each ball, whereas

on day 2, the number of balls sold were equal

to the loss on each ball. Which of these could

be the total profit (in ) made by Sonu in two

days?

Answer 2

Given:

• The number of balls sold by Sonu on day 1, was equal to the profit on each ball.

• on day 2, the number of balls sold was equal to the loss on each ball.

To find:

Total profit made by Sonu in two days

Solution:

Let the number of balls sold by Sonu on Day 1 = x

Therefore, profit on each ball = x Rs

Total profit on Day 1 will be = (profit on each ball) x (total number of balls sold) = $x^2$ Rs

Let the number of balls sold on Day 2 = y

Therefore, loss on each ball = y Rs

The total loss on Day 2 will be = (loss on each ball) x (total number of balls sold) = $y^2$ Rs

Therefore, net profit in two days will be = $x^2$ -  $y^2$ Rs

The total profit made by Sonu in two days can be calculated using this.
