Other number is 23
Step-by-step explanation:
Let the two numbers be x and y.
We have given that average of x and y is 17.
i.e 
if one of the number is 11,
Then , 
or (11 + y)/2 = 17
or 11 + y = 34

Set Y has the smaller mean. Mean means average.
Step-by-step explanation:
Set X: 20.45+28+22.25+16.5+13+18.05=118.25 divide that by 6. 118.25/6= 19.71
Set Y: 21+6+5+24+9+40= 95 divide that by 6. 95/6= 15.83
