Answer:
The new mean would be 12
Explanation:
Let the series is of 20 numbers
Given,
Mean of 20 numbers be 10
Then,
Sum of 20 numbers = Numbers × Mean
where
Numbers is 20
Mean is 10
So,
Sum of 20 numbers = 20 × 10
= 200
And 2 is added to each number, then we get
= 200 + (20 × 2)
= 200 + 40
= 240
Now, computing the new mean is as:
New mean = 240 / 20
New mean = 12
Note: Here in the question the number in a series is missing, so, I assumed 20 numbers and computed the new mean. Therefore, in the same manner any number in series could be computed.
