Question

The average of 8 observations is 24, if one more observation of 33 is added then the new average will be

Answer 1

Answer:

9

Step-by-step explanation:

Average of 8 obs. is 24

= > (sum of 8 obs.)/8 = 24

= > sum of 8 obs. = 24*8 = 192

When one more 33 is added,

Sum = 192 + 33 = 225

No. = 24 + 1 = 25

New average = (sum/no.)

New Average = 225/25

New average = 9

Answer 2

$\large\sf\pink{\underbrace{QUESTION:-}}$

The average of 8 observations is 24, if one more observation of 33 is added, then find the new average.

$\large\sf\red{\underbrace{SOLUTION:-}}$

Average Given = 24.

➝ Sum Of Observations / 8 = 24.

➝ Sum Of Observations = 8 × 24 = 192.

Now, After Adding 33.

➝ Sum Of Observations = 192 + 33 = 225.

➝ Average = 24 + 1 = 25.

New Average :-

➝ Sum Of Observations / Numbers

➝ 225/5

➝ 9.

Hence, The Answer is 9.
