But what if you take both the equations simultaneously as following 7x - 2y > 0 - Stat 1 7x + 7y > 0 - Stat 2 (multiplied by 7) -9y > 0 9y < 0 Hence, y < 0 According to this its C. Can you solve like this? (How I arrived to 7x+ 7y > 0 from Stat 2) -y < x ---- y > -x ---- y + ...

Factors cant be in negative ever . The best way to calculate the number of factors is to calculate the number of prime numbers and their powers and add 1 to them. Ex- Factors of 4 (2 X 2) Hence the number of factors will be the power of 2 i.e. 2 and + 1 = 3 For positive squares - the number of facto...

Thank you Ron!

Its crystal clear now.

Source GMAT PRep In the xy-place, line K passes through the point (1,a), L passes through the point (1,b), and both the lines pass through the origin. Is K's slope > L's Slope? Stat 1 - ab> 0 Stat 2 - |a| > |b| Please see my approach and correct me if I am wrong. (1, a) (0, 0) - Slope - a/1...

Thank you Ron!

An economist argues that this insurance is partly responsible for the high rate of bank failures, since it removes from depositors...

Some more help - The procedure for finding the standard deviation for a set is as follows: 1) Find the difference between each term in the set and the mean of the set. 2) Average the squared "differences." 3) Take the square root of that average. Notice that the standard deviation hinges o...

okay! Thank you Ron.

Ron, Thank You for your inputs!

Thank you for the explanation Ron! My Bad - I took 'upper limit' as 'lower limit' and ended up with a foot in my mouth. I thought few people are insured rather than few people are not insured . Thank you once again! @ramakrishna.doppalapoodi - The OA is right there buddy - Just highlight the text.
