उत्तर
| Commodity | Price (Rs.) | Weights (V) |
P = `"p"_1/"p"_0 xx 100` | PV | |
| 2010 (p0) |
2015 (p1) |
||||
| P | 22 | 25 | 80 | 113.63 | 9090.4 |
| Q | 30 | 45 | 30 | 150 | 4500 |
| R | 42 | 50 | 25 | 119.05 | 2976.25 |
| S | 25 | 35 | 40 | 140 | 5600 |
| T | 36 | 52 | 50 | 144.44 | 7222 |
| Total | `sum"V"` = 225 | `sum"PV"` = 29388.65 | |||
Cost of living index number = `(sum"PV")/(sum"V")`
= `29388.65/225`
= 130.62

To attain the objective the information is collected in various ways and this information is used for comparing two different time periods. For this purpose, the base year’s index is assumed as 100 and accordingly the value of the current year is calculated. Laspeyre, Paasche and Fisher have suggested different methods for constructing index numbers. |
