Question

a person sells a book for ₹5.25 and gains as much% as it's cost price is in rupees what is the cost price of the book​

Answer 1

The cost price of the book = 2.625

Step-by-step explanation:

• We have given that selling price is = 5.25

• And the person gains as much as the cost price of book, by selling the book at 5.25

Thus,

• Cost price = Gain percentage

• Cost price = Gain percentageCost price + gain percentage = Selling price

So, Let's assume that the cost price = 1 X

And then gain percentage would be = 100%

• 100 percent of 1 X is = 1 X

• And Cost price + gain percentage = Selling price

• => 1 X + 1 X = 2X

• Then, value of "x" is

• => 2X=5.25

• => 2X=5.25=> 1 X = 5.25/2

• => 2X=5.25=> 1 X = 5.25/2=> 1 X= 2.625

=> 2X=5.25=> 1 X = 5.25/2=> 1 X= 2.625The cost price of the book = 2.625
