Question

jasmine allow 4%discount on the marked price of her goods and still earns a profit of 20% what is cost price of a shirt for her marked at rupees 850

Answer 1

Given, MP of shirt = 850

Profit% = 20%

Discount = 4%

------------------------------------------------------------------------------------------------------------

MP = 100 / (100-d%) * SP

Where MP is the marked price

D is the discount

SP is the selling price

SP = MP * (100-d%) / 100

= 850 (100-4)/100

= 850 * 96/100

= 81600/100

= 816

Hence our SP = Rs. 816

Now CP = 100/(100+p%) * SP

Where CP is the cost price

SP if the selling price

P% is the profit percent

CP = 100 / (100+20) * 816

= 100/120 * 816

= 81600/120

= 680

Hence our Cost price is 680 rupees.

Answer 2

4%of 850=34
then substract it from 850=816
now 20%of 850=170then substract it from816
816-170=646 that is the cost price
