Consider the set S = {2, 3, 4, ......, 2n + 1}, where ,,n is a positive integer larger than 2007. Define X as the average of the odd integers in S and Y as the average of the even integers in S. What is the value of X ? Y? (1) 0 (2) 1 (3) ?n (4) n+1/2n (5) 2008

b

If the product of n positive real numbers is unity, then their sum is necessarily 1. a multiple of n 2. equal to n + 1/n 3. never less than n 4. a positive integer

b

1,1/2; 1,2,1/2

In a certain examination paper, there are n questions. For j = 1,2 ...n, there are 2n?j students who answered j or more questions wrongly. If the total number of wrong answers is 4095, then the value of n is 1. 12 2. 11 3. 10 4. 9

1 N=3, j=123

The number of positive integers n in the range 12 n 40 such that the product (n -1)(n - 2) 3.2.1 is not divisible by n is 1. 5 2. 7 3. 13 4. 14

b

prime number, i.e. 13, 17, 19, 23, 29, 31, 37

Choose (1) A alone. Choose (2) B alone. Choose (3) Both Choose (4) None.
