let the cp of one book is = 1rs
then CP of 10 books = 10 rs
because CP of 10 books is equal to the SP of 8 notebooks. that is why -
SP of 8 notebooks = 10 rs.
gain = 10-8
= 2
gain percentage = 2/10*100
= 20%
then CP of 10 books = 10 rs
because CP of 10 books is equal to the SP of 8 notebooks. that is why -
SP of 8 notebooks = 10 rs.
gain = 10-8
= 2
gain percentage = 2/10*100
