Q:

The average of runs of a group of 20 players in match X is 40. If the score of another player A is added to the total score of the group, the average is reduced by 1 run. After the entry of a new player, each player scores 11 runs more in match Y than his score in the previous match. Now player B joins the group and the average is increased by two runs. What is the difference between the runs scored by player A in match X and the runs scored by player B in match Y?
