A. 120
B. 121
C. 122
D. 123
E. 124
Let a = the number of advisers.
Since there are 3500 residents -- and the ratio of advisers to residents must be at least 7/200 -- we get:
a/3500 ≥ 7/200
200a ≥ 3500*7
2a ≥ 35*7
2a ≥ 245
a ≥ 122.5.
Since the value of a must be an INTEGER, the least possible value for a is 123.
The correct answer is
D.
