Religareonline people seem to be more accurate than moneycontrol.
Here is eps for particular years adjusted on face value of Rs2
05 06 07 08 09
eps 5.7 4.3 6 18 12
price 14-44 44-94 87-255 45-360 82-154
The price indicated is high low in that particular year.
For practical purposes consider 05 as the year 04-05 and so on for the high low data.
So you can calculate the pe range for the data provided and as can be seen it is all over the place and I feel it is stastically not too significant or consistent.
Currently it seems to be a good level to buy.
Biggest problem with this company seems to be the lumpiness of earnings from quarter to quarter and on year to year.
But looking at the price range for each year, if you get in at the correct price, there is almost 50% to be made each year.
