Answer» a man sold 2 articles for rs.1100 each He gained 10% on 1 ARTICLE and lost 12% 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 1100 subsituting 1100 in place of selling price and taking cost as ‘x’ 100%+ 10% =110% x + 0.10x = 1100 1.10x = 1100 x = 1100/1.10 so, profit = 0.10x = 0.10×1100/1.10 = 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

Answer»

a man sold 2 articles for rs.1100 each

He gained 10% on 1 ARTICLE

and lost 12% 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 1100

subsituting 1100 in place of selling price and taking cost as ‘x’

100%+ 10% =110%

x + 0.10x = 1100

1.10x = 1100

x = 1100/1.10

so, profit = 0.10x = 0.10×1100/1.10 = 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
