Question

The Cost price of an article for a shopkeeper is Rs.3000 . Shopkeeper marked it as Rs4000. He allows some discount on the marked price still gains 20%. What percentage discount does he allows to the customer

Answer 1

Cp=₹3000
MRP=₹4000

Profit =20%

We have two way to first the Sp and the discount

1st--

20% of 3000

=3000x20/100=600

Sp=3000+600=₹3600

2nd----

Sp=cpx(100+profit)/100

Sp=3000(100+20)/100

=3000x120/100
=₹3600

Now
Discount =MRP-SP

=4000-3600

=400

DISCOUNT %=discount/ mrp x 100

=400/4000 x100

=400/40 =10%

Discount %=10%
