Here is what I think. Original Sentence: Shoppers in sporting goods stores, unlike in department stores, do very little impulse shopping, not buying a pair of skis and a boomerang when they come in for a basketball, but they leave with a basketball only. If you see, the original sentence is only th...

Yes E is the answer... thanks Shibal and Scoobydooby

If x>y^2>z^4 which of the following statements could be true ? I> x>y>z II>z>y>x III>x>z>y IMO plugging numbers is the quickest method for these problems - the key is to *not* only try with +ve numbers only but with fractions and/or negative numbers as well. statement 1: pick x=7 y=2 z=1 so its true...

let a be the measure of angle BAO. Since AB and OC have same length, they must both have the length of OB cuz OB and OC are the radius. Since AB and OB have the same length this gives angle BOA = angle BAO = a angle OBC + angle OBA = (a + a) + angle OBA because each side adds upto 180. So angle OBC ...

IMO the answer should be 12. y takes d days to produce w so it follows that x takes d+2 days to produce w. machine y working alone produces w/d and machine x produce w/(d+2) working together for 3 days: w/d + [w/(d+2)] = 5w/12 5w/12 = 2w(d+1) / [d(d+2)] 5d^2 - 14d - 24 = 0 divide by 5 throughout d^2...

you could just plug numbers and check:

put s = 3 then we have 2^s = 8 , so in order for 2^u + 2^v be equal to 8 u and v can take the value of 2 each since 2^2 is 4 and so sum will be 8.

From the above it follows that when s = 3 , u =2 and v=2

now look at the statements ... only III holds true.

thanks. Yup 300 is the answer .. could you explain how you are calculating the thee digits-7XX,X7X,XX7

7XX- 100 times
X7X=90 times
XX7-90 times

Also, were you able to do the question in under 2 mins ?

thanks
