Question

An expression for the average of x, 2x, and 3y is ?

Answer 1

Option (D) is the correct answer.

Given:

The objective is to find the expression for the average of x, 2x, and 3y.

The average of a terms is the ratio of sum of all the terms to the total number of terms.

Then, average for the given terms can be calculated as,

`\begin{gathered} \text{Average}=(x+2x+3y)/(3) \\ =(3x+3x)/(3) \\ =(3(x+y))/(3) \\ =x+y \end{gathered}`

Hence, option (D) is the correct answer.
