Question

how much per cent above the cost price should a shopkeeper mark his items to gain 26% after allowing a discount of 10%.​

Answer 1

Answer:

marked price is 40% above cp

Step-by-step explanation:

say his cp is 100

To gain 26% he has to sell at 126

but that is after 10% discount

or 90% of initial sp=126

so initial sp was 126/0.9

=140

which is 40% above cp
