Question

4. Selling price of 6 pens is equal to the cost
price of 7 pens. Find the gain per cent or
loss per cent​

Answer 1

Answer:

Step-by-step explanation:

Let the CP of each pen be Rs.x.

Then,

CP of 6 pens=Rs.6

SP of 6 pens=CP of 7 pens=Rs.7

now,gain=SP-CP=Rs.(7-6)=Rs.1

gain%=gain/cp*100

=(1/6*100)%=16.67%

Hence,the gain=16.67%.
