Question

if the selling price of 10 pens is equal to the cost price 14 pens, find the gain percent

Answer 1

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(%)=

Answer 2

Answer:

The gain percent is 40%.

Step-by-step explanation:

Suppose Sp of 10 pens x =Cp of 14 pens

Sp of 1 pen=x/10

Cp of 1 pen =x/14

Profit %= (Sp-Cp)/Cp*100%

4x/140 *14/x*100%

40%
