Question

a shopkeeper is allowing a discount of 20% on his goods how much percent above the cost price should he mark his goods so that after allowing a discount on the marked price he gains 25%​

Answer 1

Step-by-step explanation:

Let marked price be Rs 100

Discount=Rs(

100

10

×100)=Rs 10

∴ Selling price Rs 90

Let east price beRs x

Profit=Rs

100

8x

∴ Selling Price Rs

100

108x

Now,

100

108x

=90

or, x=

108

90×100

=83.33

∴ Cost price=Rs 83.33

Amount masked above CP =Rs(100−83.33)

=416.67

∴ Percentage of masked price above CP

=

83.33

16.67

×100

=20%
