The total score of Chinese and math is 94*2= 188, so the math score is (188-X).

The sum of Chinese and English scores is 92*2= 184, so the English score is (184-X).

The sum of math and English scores is 90*2= 180.

Then the equation can be listed as (188-x)+(184-x) =180.

That is 372-2X= 180.

2X= 192

X=96

Then the math score is 188-96=92, and the English score is 184-96=88.

A: Xiaoming scored 96 in Chinese, 92 in math and 88 in English.
