The [mean] average of 5 numbers is 25, so their total is 5 x 25 = 125
The [mean] average of 4 numbers is 25, so their total is 4 x 25 = 100
→ the excluded number is 125 - 100 = 25.
Alternatively, as the average doesn't change, the excluded number must be the average, ie 25.

when the mean of ten numbers is fifteen If one of the observation is excluded the mean gets reduced by 2 the excluded number is?
132...^ i think this is wrong.reversing the operation, the sum of the original numbers must be 150.removing a number and reducing that mean value to 13 will make nine numbers that add up to 117.therefore the number that has been excluded will be the difference between the original and secondary values (150 - 117)the answer is 33.
