Question

if a selling price of 10 pen is equal to the cost price of 14 pen find the gain percent

Answer 1

Answer:

Step-by-step explanation:

Let the CP of 1 pen be rs10

Then,

CP of 14 pens will be 14×10=140

And

CP of 14 pens=SP of 10 pens

Hence..

SP of 10 pens = 140

Then,,

SP of 1 pen=140÷10=14

Gain=SP-CP. → 14 - 10→ Rs 4

Gain%=gain/CP×100

→ 4/10×100 =40%

Your ans. is 40% gain....
