Answer:
7%
Explanation:
cost of 10 bag is rs 5000.
then cost of one bag is 500.
he sold 7 bag for rs550 each then total =550×7
= 3850
again, he sold rest 3bag at cost price =500 ×3
=1500
then ,. profit percentage; s.p- c.p/5000×100
350/5000×100
= 7%
5 i think. im not good at math. sorry if wrong
percent discount = (discount)/ original * 100
= (20)/250 * 100
=.08*100
= 8 percent
He got an 8 percent discount
