Let's denote the purchase price of the product for Hari as P.
When Bina sells the product to Shyam at Rs. 4860, she incurs a 19 percent loss. So: P (1 - 0.19) = 4860 P = 6000
If Bina had sold the product to Shyam at the purchase price of Hari (Rs. 6000), she would have made a 17 percent profit. So, Shyam bought the product at: 6000 (1 + 0.17) = 7020
Shyam sold the product to Hari for Rs. 4860. So, Shyam's loss is: 7020 - 4860 = 2160
Therefore, Shyam's loss is Rs. 2160.
