Question

A shopkenepermark hisgoods 10% abovethecostprice and allowsa discountof10% .whatper cent does he gain or loss ?

Answer 1

in this there is always loss occurs

loss = (x/10)^2

whr x = % value

loss=(10/10)^2= 1% loss

Answer 2

Let assume cost price =₹100

Shopkeeper marked 10% more
So

MRP=110 <= (10% of 100=10 =cp+10)

Now he allow discount of 10%

So 10% of 110=11

Sp=MRP- Discount
Sp=110-11=₹99

Cp>sp=> loss

Loss=cp-sp

=100-99=₹1

Loss%=loss/cp x100

=1/100 x100

=1%
