Question

maths question articles are bought at RS.45 per dozen and sold at RS.85 per score . find the gain or loss per cent​

Answer 1

Given,

45 - per dozen ( 12 ) cost of 1 = 45/12 = 15/4 = 3.75

85 - per score (20) cost of 1 = 85/20 = 17/4 = 4.25

thus, profit = 4.25- 3.75= 0.50

profit percent =( 0.5/ 3.75 )× 100

50/3.75= 5000/375= 13.33%
