Barter of commodities
Verse
विपरीतीकृतमूल्ये भाण्डप्रतिभाण्डके विधिः पूर्वः ।
Translation
In (problems on) the barter of commodities, having transposed the prices (of the commodities), apply the previous rule (i.e rule of five , etc.).
Example
If 2 palas of dry ginger are obtained for 6 and one pala of long pepper for 9, how much of long pepper will then be obtained for 6 palas of dry ginger?
| Argument Side | Requistion Side | ||
|---|---|---|---|
| Cost of dry ginger → | 6 | 9 | ← Cost of long pepper |
| Quantity of dry ginger → | 2 | 1 | ← Quantity of long pepper |
| In exchange of quantity
of dry ginger → |
6 | ← How much quantity of
long pepper will get? |
Transposing the prices of the commodities, we get
| Argument Side | Requistion Side | ||
|---|---|---|---|
| Cost of long pepper → | 9 | 6 | ← Cost of dry ginger |
| Quantity of dry ginger → | 2 | 1 | ← Quantity of long pepper |
| In exchange of quantity
of dry ginger → |
6 | ← How much quantity of
long pepper will get? |
Now we have to apply the rule of five, etc. Here the fruits (i.e prices) have been already transposed and there are no denominators on any side.
