Question

if 4 was an average number of six then how would 5 become average would you add a seventh number could any one help?

Answer 1

Answer:

Yes. adding 11.

Step-by-step explanation:

Given :

4 is the average of six numbers.

Average = ( sum of the numbers )/ N

so, 4 = ( sum of the numbers )/ 6

So, the sum of the six numbers will be

6x4 = 24

But for the average to become 5 we must need to add a seventh numbers as 24 is not divisible by 5.

5 = sum of seven numbers. /7

so, the seventh number added = 35 -24

= 11.

Number added is 11.
