Question

and also last world cup game england vs sri lanka .Paul Nixon what the hell ..he was doing ? He was not palying cricket ...he need to work out some kind of new game ..?

Answer 1

The net run rate (NRR) of a side is essentially the difference between a team's run rate and their opponents' run rate.

For example:
Match 1: Team A 250/10 (50 ov) beats Team B 200/10 (50 ov)
Match 2: Team A 200/10 (50 ov) beats Team C 100/10 (25/50 ov)

In Match 1, Team A's run rate is 5.00 runs per over (rpo) (250 divided by 50), while Team B's run rate is 4.00 rpo. So Team A's NRR for this match is +1.00 (5.00 minus 4.00).

In Match 2, Team A's run rate is 4.00 rpo. However, as Team C was dismissed before the end of their innings, their run rate (for NRR purposes) is calculated as their runs scored divided by the total number of overs available. So Team C's run rate is 100 divided by 50, which is 2.00 rpo. Therefore, Team A's NRR for this match is +2.00 (4.00 minus 2.00).

For competitions such as the World Cup and England's Pro40 League, the NRR quoted on the table is an average through all matches. So, the NRR is calculated as the difference between a team's average run rate and their opponents' average run rate. That is:

(Total runs scored / Total overs faced) - (Total runs conceded / Total overs bowled)

So, combining Matches 1 & 2 above, Team A scored 450 runs in 100 overs and conceded 300 runs in 100 overs. Their NRR is therefore (450/100) - (300/100), which is +1.50.

Answer 2

total run divided by max. no of overs

For Ex: 225 runs this is 50 over match
225/50 = 4.5 runrate

225 runs this is 40 over match
225/40 = 5.625 runrate
