Bina incurs 19% loss when she sells a product at ₹4860 to Shyam, who in turn sells this product to Hari. If Bina would have sold this product to Shyam at the purchase price of Hari, she would have obtained 17% profit. Then, the profit, in rupees, made by Shyam is
Answer & solution

Answer: 2160

A 19% loss means Bina's selling price is 81% of her cost price.

So her cost price is \frac{4860}{0.81}=6000, that is ₹6000.

The hypothetical sale at 17% profit would have fetched 6000\times 1.17=7020, so Hari's purchase price is ₹7020.

Shyam bought at ₹4860 and sold to Hari at ₹7020.

His profit is 7020-4860=2160, that is ₹2160.

Shortcut. Both percentages act on the same cost price, so the gap between the two selling prices is simply \left( 117\%-81\% \right)=36\% of the cost price. That is 0.36\times 6000=2160 in one line, and the cost price itself follows from \frac{4860}{0.81}.
