Answer» Answer: 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. |
