How closely do you pay attention? Test yourself on your ability to focus (or not!). Every Tuesday, we’ll release a new brain challenge. Complete all 12 episode challenges to reveal your total brain profile.

Here’s a little sneak peek at one of the questions… there’s only three, so don’t linger too long! The idea is to answer as fast as you can!

 focus-pocus-quiz

This week, we have TWO brain challenges that correspond with next week’s TWO back-to-back premieres of the brand-new season of Brain Games. After you test your focus, explore what makes your brain tick when it comes to time. Are you sharp like a human buzz-saw? Or as focused as a swarm of drunken bees?

Take the first two brain challenges and find out! And be sure to check back next week when we release the next challenge.

Don’t miss Brain Games next Monday, April 22nd, starting and 9P… we’re going to blow your mind.

    It doesn’t say if five machines were involved in the process with one shaping the wood, one making the erasers, etc … or if five machines are all making whole pencils simultaneously. Process one means a pencil a minute. Process two means one pencil per five minutes.

    It doesn’t matter if it takes 5 machines to make one pencil or one that takes 5 minutes per pencil. you have 100 machines that makes 20 groups that produce one pencil a minute . Or one machine that makes a pencil per 5 minutes. the answer will always be 5 minutes. 20×5=100 or 100 slow machines that take 5 minutes to make one pencil. In 5 minutes you will have 100 pencils

    FRACTIONS PEOPLE
    pencils/machines
    5/5=1
    100/100=1
    therefore, they are equal fractions so whatever the answer to one is, that is the answer to the other as well. 5 minutes for each

    Every individual machine is making 1 pencil in 5 minutes. So let there be any number of machines working together time taken will be 5 minutes

    In my opinion the answer is 5minutes.

    5 machines spend 5minutes to produce 5pencils.
    It means1 machine spends 5minutes to produce 1pencil.
    so 100 machines would spend only 5minutes to produce 100pencils.

    I don’t know why this took me so long but yeah the answer is 5 minutes. There are some assumptions you have to make though:
    1) The machines are running simultaneously
    2) Each individual machine will produce a single pencil (this can be worked out from the problem)
    If it takes 5 minutes for 5 machines to produce 5 pencils, and they are running at the same time, then a single pencil will burst forth from each individual machine in 5 minutes.
    If you have 100 machines, and they’re running at the same time, and you want to produce 100 pencils, you know that in 5 minutes a single pencil will be produced from each machine. Therefore, when you have 100 machines running, it will only take 5 minutes to make 100 pencils.
