Answer 2

Correct Question :

cost price of 8 pencils = selling price of 10 pencils find gain or loss %

Answer :

Let the CP of one pencil be x and SP of the pencil be y.

ATQ:-

8x = 10y

=》 y = 8x/10.

So SP of one pencil = 8x/10 = 0.8x

An CP of one pencil = x.

So clearly we can see that the person has a loss of x - 0.8x = 0.2x.

Therefore percent of loss:-

= Loss/CP × 100

= 0.2x/x × 100

= 0.2 × 100

= 20 percent

Additional Information:

SP = Selling price .

CP = Cost Price.
