12 books' cost 72 rs
1 book's cost 72/12 rs = 6 rs
5 books' cost 5*6 rs = 30 rs
the man sold 5 books for 25 rs
the man sold 1 book for 25/5 rs = 5 rs
the man sold 12 books for 12*5 rs = 60 rs
that means he loss (72-60) rs = 12 rs
that means , (100*12/72)% = 50/3 %
1 book's cost 72/12 rs = 6 rs
5 books' cost 5*6 rs = 30 rs
the man sold 5 books for 25 rs
the man sold 1 book for 25/5 rs = 5 rs
the man sold 12 books for 12*5 rs = 60 rs
that means he loss (72-60) rs = 12 rs
that means , (100*12/72)% = 50/3 %
