Answer 1

Answer:

90 pencils

Step-by-step explanation:

If he gets,

Profit = 1/- with 1 pen

Loss = 0.5/- with 1 pencil

Then,

In 1 month he has loss of 5/- and sells 40 pens

Therefore —> 40 pens = 40/- profit

So there should be 45/- loss to get 5/- loss

Let no. of pencils = x

Then,

0.5x = 45

x = 45/0.5

x = 90

Therefore 90 pencils are sold
