Question

A shopkeeper earns a profit of Re 1 by selling one pen and incurs a loss of 40 paise per pencil while selling pencils of her old stock. In a particular month she earns neither profit nor loss. If she sold 70 pens, how many pencils did she sell?

Answer 1

Step-by-step explanation:

There is neither profit nor loss.

Profit earned + loss incurred = 0

i.e., Profit earned = - Loss incurred.

Now, Profit earned by selling 70 pens = 70 × 1 = ₹ 70

Therefore, Loss incurred by selling pencils = - ₹ 70 or - 7000 paise.

Loss incurred on each pencil = 40 paise.

Hence, total number of pencils sold=

Total loos incirred/Loss on each pencil

= -7000/-400= 175 pencils
