Question

A shopkeeper earns a profit of Rs 1 by selling one pen and incurs a loss of 40 paise per pencil while selling pencils of his old stock

i) In a particular month he incurs a loss of Rs 5. In this period he sold 45 pens .How many pencils did he sell in this period ?

ii) In the next month he earns neither profit nor incurs a loss. If he sold 70 pens, how many pencils did he sell ?​

Answer 1

Answer:

125 pencils

Step-by-step explanation:

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.
