Answer 2

Hey mate...
Here's your answer...

a number showing the variation in a price or value compared with the price or value at a specified earlier time (often represented by the number 100) is known as Index Number.
There are three types of index numbers which are generally used. They are-

1. Price Index Number---
 Helpful in measuring the prices of commodities between the current and base year.​

2. Quantity Index Number---
Helpful in measuring physical volume...

3. Value Index Number---
Helpful in measuring total value...
