Question

the avg of the set of 4 numbers is 5 a number 0 is included to the set find the avg of the new set of 5 numbers
​

Answer 1

Answer:

Step-by-step explanation:

Average = Sum of Observation / Number of observation

5 = sum / 4

sum = 20.

Now when zero is added to the data,

Sum = 20 + 0 = 20

No of Observation = 5 (as zero is a number, therefore it is also an observation)

average = sum / no of observation

average = 20 / 5 = 4

Answer 2

Answer:

1. Given the avg of 4 numbers is 5. Therefore the sum of the given 4 numbers is 4*5 = 20
2. Now if we add 0 with sum, the sum remains same but the number of total numbers becomes 5.

Therefore the avg of the new set of 5 numbers is 20/5 = 4.

So, the required average is 4.
