Questions like this always turn up on standardized tests. It's good to know how to tackle them. :)

Your casual flip-flop has a foul odor. Even age ambitious toddlers do not claim decimal ages. At most they count quarter years after their parents quit counting months. Moreover, six-years-and-eight-months is an exact answer to squirrelled question.

If Greg is Six-years-and-eight-months old, Mike would be "exactly" 20 years old, Lucy is "exactly" 17 years old, and Jane "exactly" 34 years old. Does that mean Jane, Lucy and Mike share the same birthday, and today is their birthday? Just wondering... :P

How does giving us kevins age help, and why is the answer 6.7? :evil: 6.666666 is the right answer. :evil: And if you think that 6.666666 is wrong because it isn't right down to the last nanosecond, what's wrong with 6 2/3? :evil: 2/10 for that teaser. :evil: :evil: :evil:

Can someone please explain how this is done? Here is what I did, but I can't get the right answer: J=34 K=11 L= 34/2, which is 17 M=L+3, which is 20 G= M*3, which is 60!

Jae i did the same thing and all the people that got 6.66 with a bar notation u gotta round simple as that...

Posted by pating03/10/09
jae, its M=3*G. So 20=3*G. And G=20/3.

Posted by Paladin04/09/09
You did it correctly up to "Mike is 3 times as old as Greg" You got Mike = 20, but then you said Greg = 20 *3 which would have been "Greg is 3 times as old as Mike" Instead, Greg = 20/3 = 6 2/3
