Answer 1

$\textbf {Hey there, here is the solution.}$
.............................................................................................
Let the cost price of 12 pencils be x

Selling price of the 10 pencils = x

.............................................................................................

STEP 1: Find the cost price of 1 pencil

Cost of 12 pencil = x

Cost of 1 pencil = x/12
.............................................................................................
STEP 2: Find the selling price of 1 pencil:

Selling price of 10 pencils = x

Selling price of 1 pencil = x/10
.............................................................................................

STEP 3: Find the profit:

Profit = Cost Price - Selling Price

Profit = x/10 - x/12 = x/60
.............................................................................................
STEP 4: Find the profit percentage:

Profit percentage = ( profit ÷ cost price ) x 100%

Profit percentage = (x/60 ÷ x/12 ) x 100

Profit percentage = (x/60 x 12/x ) x 100

Profit percentage = 1/5 x 100

Profit percentage = 20%
.............................................................................................

Answer: The profit percentage is 20%
