If 24X + 24Y = 192, then what is the average of X and Y?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 4.
We know that,
Average = Sum of observations/Number of observations
Given,
24X + 24Y = 192
⇒ 24(X + Y) = 192
⇒ X + Y = 192/24
⇒ X + Y = 8
The required average = (X + Y)/2 = 8/2 = 4
