Answer 2

Answer:

a) He sold 25 pencil boxes. so total profit over pencil boxes=25*10=250/-

But net loss=50/-

Means loss amount=300/-

It is due to pen. On selling one pen loss=5/-.

So for loss of 300/- he would sell 300/5=60 nos.

b) He sold 50 pencil boxes. So profit would be=10*50=500/- And this is also the loss amount due to selling of pens.

No of pens he sold=500/5=100.
