Question

if the selling price of 17 balls is equal to cost price of 16 balls find the gain percent​

Answer 1

Answer:

Hey mate!!!!

Here is your answer:

First of all, there should be loss percent not gain percent.

Step by Step Explanation:

Let the SP of 17 balls = Rs. 1

Then SP of 1 ball = Rs. (1/17)

CP of 16 balls = SP of 17 balls = Rs. 1

Then CP of 1 ball = Rs. (1/16)

Loss = (CP - SP)

        = [(1/16) - (1/17)]

        = [(17 - 16)/272]

        = [(1/272)]

Loss% = [(loss/CP)×100]%

           = [{(1/272)/1}×100]%

           = [(1/272)×100]%

           = [25/68]%

           = 0.367%
