Question

Q3. The average of following number is 5. The numbers

are 2, 3, 4, 5, 6, and x , What is the value of x ?​

Answer 1

x = 10

Explanation:

There are 6 numbers in total: 2, 3, 4, 5, 6, and whatever x is. In order for the average to be 5 in this scenario, all numbers must add up to 30, because 30/6 = 5.

2 + 3 + 4 + 5 + 6 = 20. 30-20=10. This means x would need to equal 10.

Answer 2

x = 10

Explanation:

2+3+4+5+6 = 20

(20 + x) / 6 = 5

cross-multiply:

20 + x = 30

x = 10
