Question

If the cost price of 10 pens is equal to the selling price of 10 pens. Find the gain or loss percent (℅)​

Answer 1

Answer:

this gain is 0%

neither profit nor gain

Answer 2

Answer:

Let the CP of 1 pen be Rs x

Then,

CP of 14 pens will be 14×x=14x

And

CP of 14 pens=SP of 10 pens

Hence,

SP of 10 pens =14x

Then,,

SP of 1 pen=14x÷10=1.4x

Gain=SP−CP.=1.4x−x=Rs0.4x

Gain(%)=Gain/CP×100

=0.4x/x×100

=40%
