Question

A shopkeeper earns a profit of Re 1 by selling one pen and incurs a

loss of 40 paisa per pencil while selling pencils of her old stock.​

Answer 1

Step-by-step explanation:

i) Loss = Rs 5

Profit gained by selling one pen = Re. 1

Profit gained by selling 45 pens = Rs 45

45 + x = - 5

x = - 50

So, a loss of Rs 50 has occurred while selling pencils.

No. of Pencils sold = 50 / 0.40

                              = 125

She sold 125 pencils in this period.

(ii) Profit Or Loss Incurred = 0

70 pens were sold, so profit gained = Rs 70

Cost Price Of Pencils = 70 - 0 = Rs 70

No. of pencils sold = 70 / 0.40 = 175

Therefore,

She Sold 175 pencils in the next month.
