Question

A book seller purchased 800 copies of a book for Rs.4440 . He sold copies at a profit of 20% and remaining copies at a loss of 25% . Find percentage profit/loss in the total transaction

Answer 1

Answer:

Step-by-step explanation:

4400/800

=5.5 Rs/copy

then price of 600 copies is 3300Rs

sp= cp(100+p%)/100

=3960

sp=cp(100-loss%)/100=825

total= 3960+825=4785

profit= 4785-4400=385 Rs
