Selling price = 15
profit P% = 25%
cost price = 'A' assumption
Formulae :
1. P% = [S.P - C.P/C.P]x100
25 = (15-A)/A x100 now multiply A with 25
25A= (15-A) x100
25A= 1500-100A ( multiplying with 100)
25A+100A = 1500 (shifting changes - to +)
125A = 1500 (adding both A quantities)
A= 1500/125 (when we shift 125 it becomes1/125)
A = 12
so cost price is 12
