<p>I put obsession for that one.</p>
<p>regarding the 3/11 one.</p>
<p>Let me state the question as I can remember it. </p>
<p>"There are three sets , A,B and C having different number of elements.B has twice as many elements as A and no element of A is in B.C has 1/4 th of elements of A and 1/3 rd of elements of B and no other elements. What is the fraction of elements of A that can be found in C ? "</p>
<p>Now,those who got 3/11 have assumed that A and B have the same elements but it was stated explicitly that it was not so. The question asked was about fraction of elements of A and not about fraction of number of elements of A . So,I think the answer is 1/4 . </p>
<p>Am I making sense ?? And is the question striking anyone as the one that appeared on the test ?</p>
<p>I thought the question was what fraction of C is made up of A elements</p>
<p>uhm.. even in that way , it says A elements. I dont see any reference to number of elements .</p>
<p>Okay, for the sake of figuring out this problem, we'll make up numbers.</p>
<p>Let's say:
A has 12 elements
B has twice as much as A, so 24 elements</p>
<p>C has 1/4(A) and 1/3(B)
"......" 1/4(12) and (1/3)(24)
"......" 3 A-elements and 8 B-elements
3+8=11
Of those 11 elements, 3 are A-elements
= 3/11</p>
<p>You are not getting what I'm saying. Yes ,A can 12 elements and B can have 24 . But the point is they are not the same !!! "NO element of A is in B" . They are just related by the number. For e.g. </p>
<p>I can say Ron is 12 and Hermione is 24 . But Ron is not Hermione!!!</p>
<p>And I think the question asked about elements not their number...</p>
<p>Haha I don't think you're understanding my logic either. I'm not saying that A-elements are the same as B-elements. I've kept it completely apples-and-oranges.</p>
<p>If we have 3 oranges and 8 apples, then together we have 11 pieces of fruit.</p>
<p>Of those 11 pieces of fruit, 3/11 are oranges. 3/11 of the basket of fruit is made up of oranges.</p>
<p>isn't the answer 3/11? I thought it was an easy question</p>
<p>i stand enlightened...thanks a lot to the efforts of heather to pry open my closed mind.</p>
<p>Ha and believe me, it was quite an effort. If only they had seen our msn conversation haha</p>
<p>i got obsession too...i remember putting down "everybody shud be literate" and "improve the conditions of the world" for the literature passage</p>
<p>what was the answer for</p>
<p>P-Q-R (or watever) question.. how many paths? I put 2 but my friends said its 4</p>
<p>the question was like how many ways are there from P to R but must pass through Q or something like that..</p>
<p>There were only 2 of them</p>
<p>4 man,dead sure the answer is 4</p>
<p>byebye 800...</p>
<p>u guys remember for grid-ins one answer is 72?it's the rectangle or square with a whole bunch of colored equileteral triangles inside</p>
<p>yeah.. it was 12 one side and 24 other. so it was 2x(12+24)=72</p>
<p>ok for that path question u have two choices for the 1st step,2 for the second,2 times 2 gives u 4</p>
<p>are you sure we had a same question? mine was 2 and 1 so 2x1 gave me 2...</p>
<p>and yes it was 72 :)</p>
