(a - b)^2 = 1 (a - b) = sqrt1 so a - b = 1, right? where am i going wrong? Rahul, value of (a-b) can either be 1 or -1 Indeed, In the rush of things I completely ignored that. a-b= 1 or -1 (a-b)(a-b)=1 -1 X -1 = 1 1 X 1= 1 I would have WRONGFULLY chose B as well, The correct answer is indeed E.

Sure, Here is the Explaination: The correct response is (A). The argument is essentially that the proposed law makes no sense because knitting needles are dangerous as well. The argument relies explicitly on an analogy between hypodermic and knitting needles. Thus, the two must be similar in all res...

I'll take a crack at it and say C.
The words ''profit in the long term'' hints that this answer is the best one.
I had a difficult choice with this one as I was also leaning to A.

Question: Neither a rising standard of living nor balanced trade, by itself, establishes a country's ability to compete in the international marketplace.

hypodermic needles
Hey guys, comments appreciated OA very soon :) The purpose of the proposed law requiring a doctor's prescription for obtaining hypodermic needles is to lower the incidence of drug-related deaths, both accidental and intentional, involving hypodermic needles. But even knitting needles can be lethal i...

I'm willing to take a stab at Statement 2. P- All Pets B- Birds D- Dogs 1/3P= D 1/5P= B ............................................ From Statement 2 B + 20 = D => 1/5P +20 = 1/3P 1/3P- 1/5P= 20 2/15P= 20 P=150 (all pets) From this it is sufficient to calculate Dogs 2 is sufficient

If b, c, and d are constants and x^2 + bx + c = (x + d)^2 for all values of x, what is the value of c? (1) d = 3 (2) b = 6 Is it possible to look at it from this point of view. Taking statement 1 Alone: d=3 x^2 + bx + c = (x + d)^2 , d=3 x^2 + bx + c = (x + 3)^2 expanding the RHS and comparing coeff...

Hi, I believe once it is possible to determine the length of 2 sides of the triangle and the angled formed by these 2 side, then it is sufficient. Also, if you know all 3 of the angles as well as the length of 1 side, this is also sufficient. In both cases, the Triangle is fixed, and only one such t...
