Question

The cost price of 16 books is equal to the selling price of 11 books Find the profit or loss percent​

Answer 1

Answer:

Profit% = 45.45%

Step-by-step explanation:

Let CP of 1 book be 100

Then CP of 16 books = 1600

Sp of 11 books = CP of 16 books = 1600

1600 = 11*x

x=145.45

Sp>Cp

Therefore profit of 45.45

Profit% = 45.45%

Answer 2

Answer:

45.45%

Step-by-step explanation:

Let the cost price of 1 book be x

STEP 1: Find the cost price of 11 books:

Cost price of 11 books = 11x

STEP 2: Find the selling price of 11 books:

Selling price of 11 books = 16x

⇒ It is a profit

Profit = 16x - 11x = 5x

STEP 4: Find profit percentage:

Profit percentage = 5x/11x x 100 = 45.45%

Answer: The profit percentage is 45.45%
