Using simple average of relatives method, the price index for 2011, taking 2001 as base year, was found to be 127. If Σp0=263, then x and y from the following data are :
| Commodities | A | B | C | D | E | F |
|---|---|---|---|---|---|---|
| Prices (in Rs.) in 2001 | 80 | 70 | x | 20 | 18 | 25 |
| Prices (in Rs.) in 2011 | 100 | 87.50 | 61 | 22 | y | 32.50 |
