Question

article are bought at rs 45 per dozen and sold at rs 85 per score. find the gain or loss percent

Answer 1

Hey....
Your Answer is Here,
_________________________________________________________________

cp of 12 article = 45
cp of 1 article = 45/12
cp of 1 article = 3.75


sp of 20 article = 85
sp of 1 article = 85/20
sp of 1 article = 4.25

sp >cp 
hence profit= 4.25-3.75=0.5
profit %= 0.5/3.75*100
profit %= 13.33
