Average Number | MCQs

Explanation

To find the average, we need to add the numbers and divide by the total count of numbers.

First, let's add the numbers:

0 + 0 + 4 + 10 + 5 + 5 = 24

There are 6 numbers in the list. To find the average, divide the sum by 6:

24 ÷ 6 = 4

So, the average is 4.

Explanation

Let's break it down:

(x + y + z) / 3 = 15

x + y + z = 45

(y + z + w) / 3 = 16

y + z + w = 48

Given w = 19:

y + z + 19 = 48

y + z = 29

Now, substitute y + z in the first equation:

x + 29 = 45

x = 16
