Question

if c.p of 14 pens is equal to s.p of 10 pens,then its profits percentage???

Answer 1

Let CP of 1 pen be 1 .
Then CP of 14 pens = 14
Given,
CP of 14 pen = SP of 10 pens
SP of 10 pen = 14
SP of 1 pen = 14/10 = 1.4
Profit = 1.4-1 = 0.4
Profit % = (0.4/1×100)
=>( 0.4×100)
=> 40%
hence there is a profit of 40% percent.
