A player has to play a total of five games in Round 3 of a competition. The scores for Carl's first four games are shown. Carl will qualify for Round 4 if his average score for four of the five games is 50 or more. What is the lowest score Carl must get in the 5^th game to qualify for Round 4?

Round 3
Game	Score
1st	46
2nd	49
3rd	48
4th	35
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 4, we need to exclude the lowest score (35) at the 4th game in Round 3 so that the rest of the four games can be as high as possible to qualify for Round 4.

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

Score in the 5th game
= 200 - 46 - 49 - 48
= 57

Answer(s): 57
