    Ok... a mean output is the average output.. Do you know how to find the averages?

    ok... averege is the = total sum divided by total number consider in your exam you have 2 papers... in one paper you got 40 out of 50 and in othr paper you got 42 out of 50... then using the concept of avrages can you just tell me what is your average mark?

    Your method is correct.. but answer need correction here only we have two papers..then how the total number is 4?

    cause the 91 i got by adding the 40 and the 50 and the 42 and the 50 and then dividing it by 2 and i got 91 then i just added the 40 and 42 and divided it by 2

    what you think which is more accurate.... first case you added 4 numbers (which makes total number is 4) second case you added 2 numbers (which makes total number 2)

    remember mean output is the average output..... you need to find the avrage output of each machine.... you have the total number of bags that each machine process and you know each bages weight..now you need to find the average of each machines output separatly and compare the results to obtain answer..any clue... think twice?:)
