Question

Adam sells medical magazines

Answer 1

Let the Price of 1 magzine = x

       Margin on 1 Magzine = (10%)(x) rupees = 0.1 x    

       Margin on 42 Magzines = 42(0.1 x) = 4.2 x    

Also

Let the Price of 1 books = y

       Margin on 1 Book = (15%)(y) rupees = 0.15 y    

       Margin on 14 Books = 14(0.15 x) = 2.1 y    

Basic Pay of Adam = 200

Amount that Adam earned last week = 200 + 4.2 x  + 2.1 y

2.3
