Hi
I dont know if I should put this question in the strategy section or here but here goes -:
I consistently score around 45-49 in quant and 40-42 in verbal. After browsing through these forums, I began zoning in on a more detailed analysis of my deficiency in the Quant Section. I have a tough time solving Data Sufficiency questions of a higher difficulty level ( MGMAT - 700-800 ).
How does one decide where to plug in numbers to solve a DS question or manipulate algebraic equations to get the desired result. Here's an example of what I mean -:
In the rectangular coordinate system, are the points (a, b) and (c, d) equidistant from the origin?
(1) a/b = c/d
(2) sqrt(a*a) + sqrt(b*b)= sqrt(c*c) + sqrt(d*d)
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
Both statements TOGETHER are sufficient, but NEITHER one ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
This question can be solved by plugging numbers and manipulating equations also. The reason I ask is because when I reach about question 20-22 of my Quant Section, all the questions require about the same reasonable time ( 1.30 - 2.30 minutes ). I rarely have enough time to try and formulate equations and if it doesnt work out, then try plugging in numbers. This's just one example but there're a lot more in the GMAT Prep question Pack 1 or the OG.
