Question

A cloth shop owner earns a profit of Rs.100 by selling one shirt and incurs a loss of Rs.40 per scarf while selling scarfs of her old stock.

(i) In a particular month she incurs a loss of Rs.500. In this period, she sold 45 shirts. How many scarfs did she sell in this period?

(ii) In the next month she earns neither profit nor loss. If she sold 70 shirts, how many scarfs did she sell?

Answer 1

Answer:

Correct option is

A

125

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.
