उत्तर
| Expenditure | Base Year Price 2010 (p0) |
Current Year Price 2011 (p1) |
Weight (W) |
P = `"p"_1/"p"_0 xx 100`PW | PW |
| Food | 150 | 174 | 35 | 116 | 4060 |
| Rent | 50 | 60 | 15 | 120 | 1800 |
| Clothing | 100 | 125 | 20 | 125 | 2500 |
| Fuel | 20 | 25 | 10 | 125 | 1250 |
| Rice | 60 | 90 | 20 | 150 | 3000 |
| Total | 100 | 12610 | |||
Cost of living index number = `(sum"PW")/(sum"W")`
= `12610/100`
