Detailed explanation-1: -Q. Tony-Lewis, who devised DLS method, recently passed away. DLS is a mathematical formula associated with which game? Notes: Tony Lewis devised the Duckworth-Lewis along with a mathematician Frank Duckworth, which is a mathematical formula used to determine the winner in cricket games that are affected by bad weather.

Detailed explanation-2: -The DLS methods sets targets (and decides outcomes) by calculating how many runs teams should score (and would have scored) if the resources available to both sides were equal. To calculate a target, the formula may simply be expressed thus: Team 2’s par score = Team 1’s score x (Team 2’s resources/Team 1’s resources).

Detailed explanation-3: -Definition: The Duckworth–Lewis system, devised by statisticians Frank Duckworth and Tony Lewis (and lately modified by Steve Stern), was invented in the 1990s as a replacement for alternative rules on what to do if it rained during cricket games.

Detailed explanation-4: -The DLS method is a mathematical formulation applied in case of rain or any undesirable circumstances that shortens the time of the match. The Duckworth-Lewis formula was conceived by British statisticians Frank Duckworth and Tony Lewis(hence the name) and first used in 1997. ICC adopted the method officially in 1999.

Detailed explanation-5: -The D/L method was developed during the mid 1990s and was the first to take account of the state of the match when overs were lost, i.e. both the number of overs which had been bowled and the number of wickets that were down. It came into operation at the start of 1997.
