let the cp of one book =1
then the cp of 12 book = 12
the SP of 10 book = 12
the SP of 1 book = 12/10
profit = sp-cp
= 12/10-1 =1/5
profit% = 1/5/1×100 ( profit/cp×100)
=20%
then the cp of 12 book = 12
the SP of 10 book = 12
the SP of 1 book = 12/10
profit = sp-cp
= 12/10-1 =1/5
profit% = 1/5/1×100 ( profit/cp×100)
=20%

Sp of 10 books = CP of 12 books
CP / SP

Profit= 12-10=2
Profit%= 2/10*100
