Question

Ifmean of a series is 10 and if 2 is added in every item, what would be the new mean? ​

Answer 1

Answer:

The mew mean would be 12

Answer 2

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.
