Question

a shopkeeper purchased 50 articles out of which 4 per cent were broken. still on selling he got profit eqal to cost price of 6 articles. find the profit per cent.

Answer 1

let cp on1 article be x
therefore cp=50x
profit=6x
therefore profit percent =6/50*100
=12%

Answer 2

Let's assume that article = x
So,
CP of 1 article= x
CP of 50 article= 50x
Profit= CP of 6articles
Therefore,
Profit= 6x

Profit%= profit/CP × 100
Profit%= 6/50×100
Profit%= 600/50
Profit%= 60/5
Profit%= 12%

Hope my answer helps you :)
