A player has to play a total of five games in Round 4 of a competition. The scores for Perry's first four games are shown. Perry will qualify for Round 5 if his average score for four of the five games is 50 or more. What is the lowest score Perry must get in the 5^th game to qualify for Round 5?

Round 4
Game	Score
1st	47
2nd	45
3rd	49
4th	43
5th	?

Lowest total score for four games to qualify
= 4 x 50
= 200

To get the lowest score in the fifth game to qualify for Round 5, we need to exclude the lowest score (43) at the 4th game in Round 4 so that the rest of the four games can be as high as possible to qualify for Round 5.

Hence, the 1st, the 2nd and the 3rd games must score a total of 200.

Score in the 5th game
= 200 - 47 - 45 - 49
= 59

Answer(s): 59
