Question

Articles are bought at rupees 45 per dozen and sold at rupees 85 per score. Find the gain or loss per cent. ​

Answer 1

Answer:

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
