Answer 1

bussinessman marks his goods at 30% is the
first profit
he sells them at a discount of 15% , this is the
loss for him .
at last=15per cent is the profit
so,
x=15%

Answer 2

let the cost price of his goods be 100x
profit=100x×30/100
profit=30x
SP=100x+30x=130x
discount=130x×15/100
=13×15/10
=19.5x
discounted price=130x-19.5x=110.5x
profit=110.5x-100x
=10.5x
profit percent=(10.5/100)×100
=10.5%
