In the Port-of-Spain Test between England and the West indies in March this year, there were seven centuries scored. Is it a record, or is there any instance of more centuries scored in a Test?

The seven centuries in the Port-of-Spain Test was rare, but it is not a Test record. The record is eight centuries, which was set in the 2004-05 St. John's Test between the West Indies and South Africa. Both teams scored four hundreds each in that Test.

The West Indies - England Test provided the fifth instance when seven hundreds were scored in a match. The other three instances are as follows:

What is the record for the lowest runs conceded as extras in a Test match as well as ODI?

There have been quite a few instances of no extras in an innings in Test cricket. Pakistan's total of 328 against India at Lahore in 1954-55 remains the highest without an extra.

There have been four instances in Test cricket when a side conceded only one extra in whole match. However this includes only one instance when a side dismissed the opposition in both innings and conceded only one extra. That was in the Melbourne Test in 1903-04, where England conceded only one extra in Australia's first innings total of 122 and none in second innings total of 111.

The record of least extras in a match (where both sides had a chance to bat) is two runs -- in the Lord's Test between England and New Zealand in 1958.

New Zealand holds the record of conceding least extras by a side in an ODI, in an innings of 150 or more. In the World Cup 1996 match against South Africa at Faisalabad, New Zealand did not concede a single extra in South Africa's total of 178 for five.

The record of least extras in a complete match (where both sides scored at least 100) is 4 runs between India and New Zealand at Chennai in 2003-04.
