The average of 25, 46 and ‘y’ is 11. What is the value of ‘y’?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. -38.
Average of 25, 46, and y = 11
Average = Sum of all observations/Total number of observations
According to the question -
Average = (25 + 46 + y)/3
⇒ 11 = (25 + 46 + y)/3
⇒ 33 = (25 + 46 + y)
⇒ y = 33 - 25 - 46
y = -38
