selling pencils of her old stock.
i. In particular month she incurs a loss of ^10. In this period,she sold 45 pens. How many
pencils did she sell in this period?
ii. In the next month,she earns neither profit nor loss. Ifshe sold 80 pens how many pencils
did she sell

Answer 1

Step-by-step explanation:

i) The number of pencil sold in that particular month will be:

if 1 pen gives a profit of 2 rupees then

45 pen will give a profit of 2×45= 90

and loss of per pencil is 50 paisa

A/q the loss of whole month is Rs 10

so, the loss caused by pencil= 100

( loss- profit = total loss)

( 100- 90 = 10)

A/q 2 pencil causes Rs 1 loss

? pencil causes Rs 100 loss

= 2×100=200 pencil

HENCE, The number of pencil sold in one month is 200.

ii) The number of pencil sold in the next month will be:

The profit gained by selling pen = 2×80=160

so, the loss should be also 160

As we have discussed in the above question 2×160= 320 pencils are sold in this month.
