Plzz help
How do I start and how to solve it

Answer 1

try using some easy numbers first.

if buying 10 lbs, his scale says he is only getting 11 lbs.

His selling scale says he is selling 9 lbs.

See what you can do with that.

Looks to me like he's losing money. Unless somehow the buying/selling is from the customer's perspective, not the shopkeeper's.
