Question

the mean for 24 numbers is 12.if 2 is added to every number, what will be the new mean?

Answer 1

Answer:

Therefore, The new mean is 14

Step-by-step explanation:

Mean for 24 number is given to be 12

Now, sum of 24 numbers is equal to 24 × 12

⇒ Sum = 288

Now, 2 is added to each number  and there are 24 numbers in total.

So, sum is increased by 2 × 24 = 48

Sum after increase of 2 = 288 + 48

                                        = 336

$\text{Hence, New Mean = }\frac{336}{24}=14$

Therefore, The new mean is 14
