But he broke five cups and moved 295 cups, and got 295*0.04= 1 1.8 yuan.
Only 1 1 yuan angle is obtained, and11.8-1.2 = 0.6 yuan is deducted.
Therefore, 0.6/5=0. 12 yuan = 1.2 points will be deducted for each broken cup.
If the problem is solved by an equation, it is assumed that x yuan will be lost once it is broken.
(300-5)* 0.04- 1 1.2 = 5x
x=0. 12
(2) If Xiao Ming answers question X correctly, Xiao Ming answers question (20-x) incorrectly.
Xiaoming's total score is 5x-2(20-x)=7x-40.
According to the meaning of the question, Xiao Sheng scored 7x-40+2 1=7x- 19.
The other two total scores are 15 1.
So 7x-40+7x-19 =151.
Solution, x= 15
So Xiao Ming got it right 15.
Xiao Sheng's score is 7* 15- 19=86.
Assuming that Xiao Sheng answered the Y question correctly, then
5y-2(20-y)=86
y= 18
In other words, Xiao Sheng correctly answered the question 18.
