Not sure what the "shortcut method" is, but if you can see that the data are symmetric about a middle value, that value is the mean.
Clearly, the first set has mean=7.
So, what about the 2nd set?
5,15,30,40,45,55,60
Hmmm. Not so clear. Better explain what your method involves.
the following data relate to size of shoes sold at a store during the given week find the average size by the short cut method
size of shoes. 4,5,6,7,8,9,10
no of shoes 15,30,45,60,55,40,5
