It was an emergency call.

3mar · Answer

This problem is related to mean value or arithmetic mean.

3mar · Answer

It is calculated with the form:
For a, b, c, d, e, and f, the arithmetic mean is$$\frac{ a+b+c+d+e+f }{ 6 }$$
where 6 represents the number of items you are calculating the arithmetic mean for.

3mar · Answer

For our case:
calculate the arithmetic mean for the first three games; we get
$$\frac{ 192+214+250 }{ 3 }=218.667$$
then he needs to win the fourth game with minimum score x to get the average score of 225
so the arithmetic mean of x and 218.66 will be 225
$$\frac{ 218.667+x }{ 2 }=225$$
$$x=231.333$$
so the fourth game score should be at least 232
