Question

the s.p of 10 article is equal to the c.p of 8 articles .find the profit or loss in percent ??

Answer 1

as the sp is smaller than cp for same quantity it is of loss..1.25 percent

Answer 2

let sp of 10 article be m
cost of 1 article =m\10
thus s.p of 8 article =m
sp of one article m\8

cp>sp
therefore loss
loss=loss×100÷c.p

loss=m\8-m\10
loss=5m - 4m÷40
loss=m\40
loss%=m\40×100\m\10
loss%=25
loss=25%
