Question

A shopkeeper earns a profit of rs 5 by selling one notebook and incurs a loss of rs 1 by selling an old pen. In a particular month the shopkeeper earns a profit of rs 185 . If he sold 75 pens, find the number of the notebook sold .

Answer 1

Answer:

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

THIS IS AN EXAMPLE
