Answer 2

mark me as brainliest

Step-by-step explanation:

Loss per pencil 40 paisa.

Loss for 70 pencils = 70 × 40 = 2800 paisa = 28 Rupees.

So, to recover the loss of 28 rupees , 28 pens should be sold as each pen gives profit of 1 rupee

Ans.: 28 pens

p.s.: 5 pencils cause loss of 200 paise = 2 rupees. 2 pens cause profit of 2 rupees So, for every 5 pencils sold, 2 pens should be sold to ensure that no loss occurs.
