Mean = Sum of Observation/Total Number of Observation
Calculations:
The mean of five numbers is 18
∴ Sum of Observation = 5 × 18 = 90
If one number is removed the mean is 16.
∴ Total number of Observation = 4

Sum of new Observation - Sum of Observation = 90 - 64 = 26 (The Number removed from the data)
Hence, The Correct Answer is 26.
