A player has to play a total of five games in Round 3 of a competition. The scores for Ahmad's first four games are shown. Ahmad will qualify for Round 4 if his average score for four of the five games is 90 or more. What is the lowest score Ahmad must get in the 5^th game to qualify for Round 4?

Round 3
Game	Score
1st	89
2nd	86
3rd	86
4th	79
5th	?

Lowest total score for four games to qualify
= 4 x 90
= 360

To get the lowest score in the fifth game to qualify for Round 4, we need to exclude the lowest score (79) 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 360.

Score in the 5th game
= 360 - 89 - 86 - 86
= 99

Answer(s): 99
