1 percent cost how many marks?
Consider the total marks be 100.
For every correct answer, one mark is scored.
Hence, 1 percent cost 1 marks.
A shopkeeper marks his goods at 30 percent above the cost price and then gives a discount of 10 percent. Find his gain percent.
How much percent above the cost price should a shopkeeper mark his goods so that after allowing a discount of 10% on the marked price, he still gains 8%.
