Hi, I am not sure of a general way but the way I would do this problem is as follows: since x<8/9 and y<1/8. x+y has to be less than 8/9+1/8 i.e, x+y<73/72 x+y<73/72 doesnt necessarily mean x+y<1. it could be 1.00000009 or some value less than 73/72 but greater than 1. so, my answer would be (E).

ok here you go:

1st day - 0.1
2nd day - either 0.4(0.1+0.3) or 0.2(0.1 x 2) . We choose the least so 0.2
3rd day - either 0.5(0.2 + 0.3) or 0.4(0.2 x 2). We choose 0.4
4th day - either 0.7(0.4 + 0.3) or 0.8(0.4 x 2). We choose 0.7

Ans is 0.7

Let me know if u have quest.

sorry, my answer is C.. not B. I just realised. Ya u r right, passive construction needs to be avoided... but in this case, all other choices are even worse. C is the best among all others.. Here is my analysis... A)"believed to be" seems to be modifying 36 feet, since its immediately after 36 feet ...

According to me the answer should be 9/15 = 3/5 4/9 looks wrong to me. Reason being, he is simple taking 2/3 * 2/3 = 4/9 Doesnt make sense... Here is how I get 3/5 - Denominator - Total no of ways to get 4 children = 6C4 Numerator - Total no of ways to select 2 girls of 3 * Total no of ways to selec...

IMO Ans is (E) Stmt 1 alone is not sufficient as it talks only about p Stmt 2 is not sufficient as it talks only about q. Stmt 1 and 2 together may give some information, but there can be different cases such as p>q, when p=0.45 and q=0.4 p<q, when p=0.2 and q=0.45 p=q, when p=0.45 and q=0.45. Since...

My answer is (B) 210pi + 280 Here is the solution: total length of cord = length of cord(s) between the circles + length of cord surrounding circle 1 + length of cord surrounding circle 2 Length of cord between circles = (80 + 60) + (80 + 60) = 280. [ As you can see its forming squares on both sides...

I agree.. It will be fun... all coders get together... but ofcourse ONLY after my GMAT ;)


The question seems incomplete. What do you have after "if" at the end? However, I can write the equation needed to solve this question. Substitute the values and you should get the answer.
