Answer:

Step-by-step explanation:

Given:

Ishita sold a book worth₹200 to Rohan at a profit of 10% .Rohan sells it to Rishi for loss of 10% .

To Find:

How much Rishi paid for book​.

Solution:

Cost price of book = 200

Profit = 10%

==> 10% of 200

==> 20

Selling price = 200 + 200 = 220.

Loss = 10%

==> 10% of 220

==> 22

Selling price = 220 - 22 = 198

Result:

Rishi paid 198 for book​.

Answer 2

Rishi paid Rs 198 for the book.

Explanation:

Case-1:

C.P. = Rs 200

Profit = 10%

∴ Profit = Rs(200×10/100)

            = Rs 20

∴ S.P. = Rs (200+20)

         = Rs 220

∴ For the book Rohan pays Rs 220.

Case-2:

C.P. = Rs 220

Loss = 10%

Loss = Rs (220×10/100)

        = Rs 22

∴ S.P. = Rs (220 - 22)

         = Rs 198

∴ Rishi paid Rs 198 for the book.
