Goods which are traded in large quantity and are not purchased by ordinary consumers. The price measure of such trading is known as ........

Whole Sale Price index.

The correct answer is Option (1) → Whole Sale Price index.

Goods that are traded in large quantities and not directly purchased by ordinary consumers are measured through the Wholesale Price Index (WPI). The WPI reflects the average change in prices of goods at the wholesale level, i.e., before they reach the retail market. It is commonly used to track inflation trends in bulk trade and industrial goods.

"...many commodities have two sets of prices. One is the retail price which the consumer actually pays. The other is the wholesale price, the price at which goods are traded in bulk. These two may differ in value because of the margin kept by traders. Goods which are traded in bulk (such as raw materials or semi-finished goods) are not purchased by ordinary consumers. Like CPI, the index for wholesale prices is called Wholesale Price Index (WPI). In countries like USA it is referred to as Producer Price Index (PPI)."
