Number of longterm employees is 70% of 800 = 560 Y is the number of longterm employees who are leaving What value of y would reduce the number of long term employees to 60% of 800 = 480 Hence the difference between 560 and 480 = 80 is the answer. These are the number of y employees who have to leave the company.

How abt this. If we replace x in y - x with the value of x from St 2), we get 2y - 1, now using st 1), we know that y > 0, hence 2y - 1 has to be positive.

Is y – x positive? (1) y > 0 (2) x = 1 - y A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. C. 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. IMO the answer is © but the OA is (E). Please could someone explain.

IMO it should be (B). (B) uses or instead of and. Uses had been as the tense. © and (D) are awkward. (E) changes the tense of the snetence at the end. What is the OA?

IMO the answer is (E).

Thanks for the fantastic solution.

Thanks for the solution and concept atishree.

Start solving the GMAT Maths Sets.

The right answer is (D). By the way, how did you go about solving it?

I think, I have figured this one out. The answer should be (b). The first statement will not suffice. Since r is greater than 100, it could take a value of 288 as well and then the hours will be less than 10. But if r were 101 then the job would take more than 10 hours. We do not have a clear cut answer with statement (1).

Even I go with (E). But the OA is given as ©. This question is from GMAT Math Set 21.

Thank You!!! Looks like another careless mistake from my end.

If x2 + y2 =1, is x + y =1? (1) xy =o (2) y = 0 (A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. (B) Statement (2) ALONE is sufficient, but statement (1) alone 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. Please could someone explain how the answer is (E).

What is the median number of employees assigned per project for the projects at Company Z? (1) 25 percent of the projects at Company Z have 4 or more employees assigned to each project. (2) 35 percent of the projects at Company Z have 2 or fewer employees assigned to each project. (A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. (B) Statement (2) ALONE is sufficient, but statement (1) alone 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.
