Question

vikas bought 20 pens for rupees 8 each .he sold these pens for rupees 10 each .find his profit or loss per cent .​

Answer 1

Answer:

C.P. of 1 pen = 8 rupees

C.P. of 20 pens = 20 * 8 rupees

= 160 rupees.

S.P. of 1 pen = 10 rupees

S.P. of 20 pens = 20 * 10 rupees

= 200 rupees.

Now,

Profit = S.P. - C.P.

= 200 rupees - 160 rupees

= 40 rupees.

Profit % = Profit / C.P. * 100

= 40 / 160 * 100

= 25 %

Hence ,

Profit % = 25 %
