Is m^2/n0?

Question

Is \frac{m^2}{n} >0? 1) m-2n>1 2) 2

suchita2409 · Answer

C

Statement 1 is insufficient because we do not know the value of n.n can be +ve or -ve.

Statement 2 is insufficient because we do not know either m is 0 or +ve. Because squares are non negative

1 + 2 provides the solution.

#1 m-2n>1 value of n could be +/-ve and then we get both yes & no to \frac{m^2}{n} >0? insufficient #2 20 sufficient IMO C

Is m=0 a solution to this inequality?

If x>0 then is x=0 a solution?
If m^2 > 5^2 then m=5 a solution?
If m^2 > 0 then m=0 a solution?

One need not find the exact value of variable in Data Sufficiency question.

A GMAT data sufficiency question is made up of a question and two statements, labeled (1) and (2). Your job is to decide whether the data given in each of the statements is sufficient (enough) to answer the given question.

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

What is meant by "this" inequality in your doubt? Are you asking a new question or the question in thread?

For the question in thread,

In is....? Type questions, one need to answer in Yes or No.

If m =0, is m²/n>0? Reduces to is 0>0?
 Answer is No

If m not =0 and n >0, answer is Yes

One need not find exact value of m. In fact, for the above Question, exact value of m can not be determined.

Even a definite NO is alao taken as sufficiency

2 conditions are necessary for \frac{m^2}{n} >0 1. m is non zero 2. n is positive 1) m-2n>1 Or n<\frac{m-1}{2} If m=0, NO If m=10 and n=1, YES 1 is not sufficient 2) 22n+1 so m is positive Since m and n are both positive, \frac{m^2}{n} >0 is true Sufficient Answer is (C) Posted from my mobile device
