Step 1: Let the purchase price of the product for Hari be \( P \).
Step 2: Bina sells the product to Shyam at a 19% loss. She sells it for ₹4860.
That means: \[ P \times (1 - 0.19) = 4860 \Rightarrow P \times 0.81 = 4860 \Rightarrow P = \frac{4860}{0.81} = 6000 \] So, the purchase price of the product for Hari is ₹6000.
Step 3: Bina would have made a 17% profit if she had sold the product at ₹6000.
That means the price at which she bought the product (from someone else) is: \[ \text{Cost Price for Bina} = \frac{6000}{1 + 0.17} = \frac{6000}{1.17} \approx 5128.21 \] But in this case, we don’t need Bina’s cost price. Instead, consider this:
If Shyam had bought the product at ₹6000 (Hari’s cost), he would’ve incurred a 17% profit for Bina.
So, \[ \text{Shyam’s Cost Price} = 6000 \times (1 + 0.17) = 6000 \times 1.17 = 7020 \]
Step 4: But Shyam sold the product to Hari for ₹4860.
So his loss is: \[ 7020 - 4860 = \boxed{2160} \]
Final Answer: Shyam incurred a loss of ₹2160.
