After assessment, Leo’s average score of Chinese and English is 85. When he got his math result, he worked out that the average score of the subjects is five points more than the average of previous two subjects. What is Leo’s math score?
Let's represent Leo's score in Chinese as C, English as E, and Math as M.
Given that Leo's average score in Chinese and English is 85:
(C + E) / 2 = 85
C + E = 170
Also, given that the average of the three subjects is five points more than the previous two:
(170 + M) / 3 = 85 + 5
(170 + M) / 3 = 90
170 + M = 270
M = 270 - 170
M = 100
Therefore, Leo's math score is 100.
