Profit earned by selling 1 pen = Re 1

Profit earned by 45 pens = Rs. 45, which we denote by + Rs. 45

Total loss given = Rs. 5, which we denote by Rs -5.

Profit earned + Loss incurred = Total Loss

Therefore, loss incured = Total Loss - Profit earned.

= Rs. (-5-45)

=Rs. (-50)= -5000 paise

Loss incurred by selling one pencil = 40 paise, which we write as -40 paise.

So, number of pencils sold

= (−5000) ÷ (−40) =125 pencils.

Answer 2

Answer:

pen is profit Rs, 1, profit 45 pens = Rs. 45, profit in positive then loss for month = -5; 45 + x = -5; x = -45 + -5=-50;; pencil sold = ( 50 / 0. 40) =125.
