Question

Book seller bought a book for Rs 20 and spend rupees 5 on its binding he sold it for RS 30 find his gain or loss percent

Answer 1

Answer:

CP = 20+5

=25 rupees

SP = 30 rupees

SP                                                  CP

30 rupees                  >                   25 rupees

gain percent = SP/100

=30/100

=0.3% gain

SP is more than CP . Then it mean that the book seller got a gain.
