# How to Calculate Profit and Loss (Page 4/4)

(Contiued from page 3 )

Question - Type 6 -

The Marked price of a ball is Rs 300/-, but the seller sell it to you for Rs 270/-. Find the discount provided and discount %.

Answer - 6-

The difference between Marked price and actual selling price

= 300-270 = 30 is discount.

Discount % = (30/300)*100 = 10 i.e. discount is 10 %

Question - Type 7 -

Marked price of a table is Rs 300. Seller sells it at a discount of 20% and still earns a profit of 20%. What is the C.P.

Answer - 7-

S.P. = (M.P.) - (M.P. * Discount %)/100

= 300 - (300 * 20)/100 = 300 - 60 = 240

Profit % = 100 * (S.P. - C.P.)/(C.P.)

i.e. C.P. = (100 * S.P.)/(100 + profit %)

= (100 * 240)/(100+20) = 24000/120 = Rs 200

Question - Type 8 -

If market price is Rs 525/- and Cost Price is Rs 500/-. What is max discount margin available.

Answer - 8-

The Profit margin available is 525-500 = Rs 25/-

Max discount margin is where profit= 0

therefore max profit margin = (Profit * 100) / C.P.

= 25 * 100 / 500 = 5 %
