You can put this solution on YOUR website! The mean of 12 numbers is 18.
If each of the first 6 numbers is increased by 2 and each of the remaining numbers is also increased by 4,
obtain the new mean of the 12 numbers.
:
initially the average can be written which is 18 obviously
:
add 2 to the 1st 6 values of 18 and 4 to last 6 values of 18
A =
A =
A = 252/12
A = 21 is the new mean
