Question

Which of the following represents "the average of 171 and x"?

(x + 2)/171
(171 + x)/2
(171 - x)/2

Answer 1

We that the average of anything is ratio of the sum of the quantities to number of quantities.



Here, in the question ,



Quantities = 171 and x


Sum of quantities = ( 171 + x )
Number of quantities = 2 that are 171 and x





Hence,

$Average \: of \: 171 \: and \: x = \frac{their \: sum}{2} \\ \\ \\ \boxed{ \bold{Average \: of \: 171 \: and \: x = \frac{171 + x}{2} }}$





Option C is correct.
