please give step by step answer please​

Answer 1

Step-by-step explanation:

let the price of the 10 pencils be 100

price of 1 pencil =100÷10

=10

S.P of 8 pencils =10×8=80

Therefore loss

100-80

20

Answer 2

Answer:

Let CP of one pencil be x.

CP of 10 pencils=10x.

SP of 8 pencils=CP of 10 pencils=10x

SP of 1 pencil=10x/8=5x/4

Here SP is more than CP so there is a profit.

Profit=SP-CP

=5x/4-x

=x/4

Profit%=(Profit/CP)*100

=(x/4×1/x)*100

=25% profit......
