Question

If a book is sold for rs 1800at a loss of 10%if the same book was sold for rs 2400 what would have been profit or loss percentage

Answer 1

sp=1800

loss%=10%

cp= let the cp be x

x/1-10x/100=1800

x/1-x/10=1800

10x/10-x/10=1800

9x/10=1800

9x=18000

x=18000/9=2000

now,

cp=2000 rs

sp= 2400 rs

clearly, sp is greater than cp so profit

profit=sp-cp=2400-2000=400 rs

profit %=profit/cp*100=400/2400*100=16.66% profit

pls mark as brainliest answer....
