Question

if a person buys 8 pens for 80 rupees and he sells 4pens with profit of 3 per pen and 3 pens with a loss of 2 per pen at the buying cost, find the total loss or profit

Answer 1

cost of 1 is equal to 80/8=10

he sells 4pens with a profit of 3 per pen

profit on one pen =3

profit on 4 pen = 3× 4=12

loss for 3 pen =2 per pen

loss for 1 pen=2

SP of 4 pen =13×4

=52

SP of 3pen=8×3

= 24

total SP =24+52=76

loss=CP-SP

=80-76=4 answer
