Greate Score Arjmen!! Thanks for all your help :tup: :tup:

This is my take on the problem. We need the coordinates for the center of the circle first . assuming center = (h,k) stmt 1: (h-2)^2 + (k-4)^2 = (h-5)^2 + (k-10)^2 resolves to some equation of the form ah + bk + c = 0 (no need to solve) insuff stmt 2: (h-2)^2 + (k-4)^2 = (h-4)^2 + (k-1)^2 resolves to some equation of the form ph + qk + d = 0 (no need to solve) insuff combine 1 and 2 => Gives the values for h and k and the center (h,k) Now radius can be determined by finding the distance between (h,k) and any other point on the circle (no need to solve), answer yes or no . Hence sufficient Go with C

Great sourabh! , good explanation thanks. This one bit me....

At a bakery Lew spent a total of $6.00 for one of kind of cupcake and one kind of dougnut. How many dougnuts did lew buy ? 1) The price of 2 doughnuts was $0.10 less than the price of 3 cupcakes 2) The average (mean) price of 1 dougnut and 1 cupcake was $0.35

Should be E A,C, D make the same mistake of comparing novels with authors. Novels should be compared with novels. B is incorrect since it changes the meaning to say ' Jean Toomer’s Cane ' includes the rest plus the usage is wrong

E is correct Is x^4 + y^4 > z^4? 1. x^2 + y^2 > z^2 2. x + y > z stmt 1: Let x^2 = 3 , y^2 = 4, z^2 = 5 (sides of a right angled triangle) Then x^4 + y^4 = z^4 , 9 + 16 = 25 (can be equal) for some other valuese.g (1,4,1) x^4 + y^4 > z^4 hence insuff stmt2: Let x = sqrt(3) , y =sqrt(4) =2, z = sqrt(5) Then as in stmt1 x^4 + y^4 = z^4 , 9 + 16 = 25 (can be equal) for some other valuese.g (1,4,1) x^4 + y^4 > z^4 hence insuff No additional information on combining stmt 1 and stmt 2 still insuff hence E

james, do not forget about 1 and the number itself e.g 34 , factors 1, 2,17,34 34 -2 = 32 (even), hence OA is right, only 2 satisfies B

Supratim, here is my take on this via POE: (A) A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass. - here it is ambigious, is it referring to white dwarf, neuton star or star (B) After passing through a red giant stage, depending on its mass, a star will compress itself into a white dwarf, a neutron star, or a black hole. - Sequence of events wrong, Changes meaning, mass has to be determined first before passing through the red giant stage © After passing through a red giant stage, a star’s mass will determine if it compresses itself into a white dwarf, a neutron star, or a black hole. -Misplaced modifier issue, 'After passing through a red giant stage' seems to be modifying star's mass , should be the star . Plus carries forward the same problem as in B (D) Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole. -Correct choice (E) The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole. -Again misplaced modifier issue, 'after passing through the red giant stage' is incorrectly modifying the mass of the star. Plus distorts the meaning to say that the 'mass of the star' is passing through the red giant stage

If 500 is a multiple of 100 that is closest to X and 400 is the multiple of 100 that is closest to Y , which multiple of 100 is closest to X + Y ? 1) X 2) Y Is the measure of one of the interior angles of a quadilateral ABCD equal to 60 degrees ? 1) Two of the interior angles of the quadilateral ABCD are right-angles 2) The degree measure of angle ABC is twice the measure of angle BCD

Struggled between B and D, will go with D B is out of scope, talks about hierarchical work environments

Go with A If this was not true , the sales of the books couldn't have gone up.

Only 1 is true 'At least one home was sold for more than 165,000'

Will go with E for better expression, A looks wordy Good catch kamal_forGMAT! D it is

A seems right Associating two conditions ( shorter workweeks and control over life) as cause and effect on the basis of their being causally associated with the same phenomenon(reduced stress)

Thanks piyusht, frankly I would have gone for B on a real test
