hello - I see why all the other choices are wrong, but can somebody please explain how come C is correct. is it not ackward: led to the passage in 1999 of the Anti-Cybersquatting Consumer Protection Act

If n and p are positive integers, what is the ratio of n to p? (1) np = 48 (2) p2 – n2 = 28 (A) Statement (1) ALONE is sufficient, but statement (2) is not sufficient. (B) Statement (2) ALONE is sufficient, but statement (1) is not sufficient. © BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. (D) EACH statement ALONE is sufficient. (E) Statements (1) and (2) TOGETHER are NOT sufficient.

Bose is correct. B it is.

OA is A and I believe it should be wrong. i am also getting E.

Answer can not be A. Firstly, it is not given that x is an integer. so it is very much possible that x^5 = 2, which satisfying the condition but that means x = (2)^1/5 - this is not even. So A alone is not good. Also, second statement is not enough because for the reason coolstrugler explained. So answer can be C or E. Answer should be C. If you try out any value which satisfy both the condition, it will even! for example 0, 2, 4...and for all the fractions and odds it will not satisfy.

x is the sum of y consecutive integers. w is the sum of z consecutive integers. If y = 2z, and y and z are both positive integers, then each of the following could be true EXCEPT 1. x = w 2. x > w 3. x/y is an integer 4. w/z is an integer 5. x/z is an integer

For any integer k > 1, the term “length of an integer” refers to the number of positive prime factors, not necessarily distinct, whose product is equal to k. For example, if k = 24, the length of k is equal to 4, since 24 = 2 × 2 × 2 × 3. If x and y are positive integers such that x > 1, y > 1, and x + 3y 1. 5 2. 6 3. 15 4. 16 5. 17

A school must raise exactly $2,500 over the next year by investing $30,000 in stocks, which yield 9% annual interest, and bonds, which yield 8% annual interest. If the school wants to invest as much as possible in stocks, then how much should the school invest in stocks? (A) $1,000 (B) $10,000 © $20,000 (D) $29,000 (E) $30,000
