Answer:
I would say he makes 10.5%
Explanation:
Let the price at which the shopkeeper bought the article be 100.
Since he has to make a profit of 30%, he would mark the price as 130.
Now, he allows a discount of 15% i.e. 15% of 130 = 19.5
The actual discounted price= 130–19.5= 110.5
He gets 10.5 on 100. The profit percent he makes is 10.5%
