Answer:

c. h+j+k over 3

Step-by-step explanation:

We know that,

\text{Average}=\frac{\text{Sum of observations}}{\text{Total number of observation}}

Here, h, j and k represents the melting point of helium, hydrogen and Neon respectively,

Since, the sum of melting points = h + j + k,

Also, the total number of gases = 3,

Thus,

\text{Average melting points}=\frac{h+j+k}{3}

Or (h+j+k) over 3

⇒ Option c is correct.

Average = mean = sum of the values / number of data

Values = h, j, and k

Number of data = 3

Sum of the values = h + j + k

Mean = [h + j + k] / 3

=> Answer: option c. [h+j+k] over 3
