Sandeep purchased 100 articles at rate Rs 10 per article.If he sold 50% articles at 20% profit while 50% of remaining at 10% profit 20% of remaining at 10% loss and rest at 20% loss.Find his loss or profit percent in entire transaction.

____________________

He gained 10% on 1 article

and lost 10% on another article

for the first article, if he gained 10% that means,

Cost + Profit = Selling Price

100% + 10% = 110% ( as we know profit is 10% of Cost)

Now we know, selling Price is 1000

subsituting 1000 in place of selling price and taking cost as ‘x’

100%+ 10% =110%

x + 0.10x = 1000

1.10x = 1000

x = 1000/1.10

so, profit = 0.10x = 0.10*1000/1.10 = 90.9090909

Now repeat same process for loss

100% - 10% = 90%

taking cost as x

x - 0.10x = 1000

0.90x = 1000

x = 1000/0.90

so loss = 0.10x = 0.10*1000/0.90 = 111.111111

Finally as u can see loss is more than profit

net loss will be 111.111111 - 90.9090909 =20.2020201

Hope This Helps
