Question

The cost of 11 pencils is equal to the selling price of 10 pencils. Find the loss or profit percent.

Answer 1

Cost of 11 pencil = s.p of 10 pencil

Let the cost of 11 pencil be x
So, cost of 1 pencil = x/11

As follows, s.p of 10 pencil = x
So, s.p of 1 pencil = x/10

So, profit = s.p - c.p
=x/10 - x/11
=(11x - 10x)/110
=x/110

So,profit% = profit/c.p x 100
=x/110 ÷ x/11 * 100 %
=x/110 * 11/x * 100 %
=10%

Answer 2

Answer:

=10%

Step-by-step explanation:

ost of 11 pencil = s.p of 10 pencil

Let the cost of 11 pencil be x

So, cost of 1 pencil = x/11

As follows, s.p of 10 pencil = x

So, s.p of 1 pencil = x/10

So, profit = s.p - c.p

=x/10 - x/11

=(11x - 10x)/110

=x/110

So,profit% = profit/c.p x 100

=x/110 ÷ x/11 * 100 %

=x/110 * 11/x * 100 %

=10%
