(E) 63
what is the greatest possible value of n ?
Greatest possible value of n is possible when mean is 21
So 21*3 = 63
63-(16+20) = 27
Hence C
Another Approach,
By logic D & E are not possible bcoz mean = between 18 and 21
and if you take n= 18 it will be not greatest possible value of n

Note : we must take such a value of n for which the average must be in between 18 to 21, inclusive. It means 21 can be the average . We are looking fro greatest value of n. So, we must take 21 as average of this 3 numbers.
16 + 20 + n = 3*21
36 + n = 63
n = 27.
The best answer is C.
