A number X is 60% of the average of 20, 28 and 36. What is the value of the number X?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 16.8.
We know that,
Average = Sum of observations/Number of observations
The average of 20, 28 and 36 = (20 + 28 + 36)/3 = 28
⇒ 60% of X
⇒ 60% of 28 = 16.8
