Problem |
The mean score of 8 players in a basketball game was 14.5 points. If the highest individual score is removed, the mean score of the remaining 7 players becomes 12 points. What was the highest score? |
|
2 |
Step |
Let’s represent the highest score as x. |
|
3 |
Step |
The average score of 8 players in a basketball game is |
14.5 points |
4 |
Step |
The highest individual score is removed, and the mean score of the remaining 7 players becomes |
12 points |
5 |
Step |
Calculate total points: The total points scored by all 8 players is |
\$8 \times 14.5\$ = 116 |
6 |
Step |
Calculate total points without the highest score: The total points scored by the remaining 7 players is |
\$7 \times 12\$ = 84 |
7 |
Step |
Find the highest score: The highest score (x) is the difference between the total points scored by all 8 players and the total points scored by the remaining 7 players |
x = 116 - 84 x = 32 |

Solution |
So, the solution is that the highest score was 32 points. |

Choice-A |
If the highest score were 20 points, then the total points scored by all 8 players would be \$8 \times 20 = 160\$. However, this contradicts the given mean score of 14.5 points for all 8 players |
Wrong 20 |
11 |
Choice-B |
If the highest score were 24 points, then the total points scored by all 8 players would be \$8 \times 24 = 192\$. Again, this contradicts the given mean score of 14.5 points for all 8 players |
Wrong 24 |
12 |
Choice-C |
As we’ve calculated previously if the highest score were 32 points, then the total points scored by all 8 players would be \$8 \times 32 = 256\$. This fits with the given mean score of 14.5 points for all 8 players, satisfying the conditions of the problem |
Correct 32 |
13 |
Choice-D |
If the highest score were 36 points, then the total points scored by all 8 players would be \$8 \times 36 = 288\$. This also contradicts the given mean score of 14.5 points for all 8 players |
Wrong 36 |
