The average of x and y is 16 and the average of x, y, and z is 2What is the value of z?
选项
A、16
B、22
C、34
D、45
E、66
答案
C
解析
The correct answer is C. You are given that the average of x and y is 16. Therefore,(x+y)÷2 = 16, which means that x+y=32. It is not important to know what x and y equal individually, only to know that their sum is 32. Given that the average of x, y, and z is 22, then(x+y+z)+ 3 = 22, and x+y+z=66. Since x+y=32, then 32+z=66, and z=34.
