5 6 7 10 4 15 12
The average is 15.
If the average is 10 then 15 is 5 above average.
Average(5, 10, 15) = (5 + 10 + 15)/3 = 30/3 = 10
LCM(10, 12, 15) = 60.

The average is 15.
12. This is because you add the numbers and then divide by the amount of numbers to get an average. So here we add the numbers and divide the total by 3. 10+11+15 = 36. 36/3 = 12.
