The total score of three people was 228 points.
Taro's score was 18 points higher than Jiro's score.
The average score of Taro and Jiro was the same as a score of Hanako.
Find Taro's score.
Answer
85 points
Solution
Accordning to Taro + Jiro + Hanako = 228 and Taro + Jiro = Hanako × 2, Hanako × 3 = 228.
Thus Hanako = 228 / 3 = 76.
Taro + Jiro = 76 × 2 = 152
Taro - Jiro = 18
Therefore Taro = (152 + 18) / 2 = 85 points.
