If the average of 201, 202, 204, 205, 206, 209, 209, 210, 212 and x is 207, what is the value of x? Choose the correct choice from the following answers:
A) 207
B) 209
C) 211
D) 212
E) 213
Sum of the deviations of the numbers in the set from the mean is always zero   201, 202, 204, 205, 206, 209, 209, 210, 212   mean is 207   so the list is -6-5-3-2-1+2+2+3+5... this shud total to zero   but this is -5 , hence we need a number that is 5 more than the mean to get a +5 and make it zero   hence the answer is  207+ 5=
