The average score of Li Hua's Chinese and English is 80.5, and the average score of English has increased by 10.5 after the math score was announced. How many points did Li Hua get in the math exam?
Let's put it this way. Because English and Chinese scores are not required, let's assume that China people get 80.5 in English and X in math.
The average score of English increased by 10.5, 80.5+ 10.5 = 9 1, and the average score of English in China was 80.5.
So 9 1× 3 = 80.5× 2+x, x = 1 12, so the math score is 1 12.
