Are you Smarter then a 5th Grader?


Bermudian

Recommended Posts

Ok guys I have a really good math problem.

 

This is a real 5th grade math problem.

I'm really good at math so I got it in 2 minutes.

 

Lets see if you can figure it out.

 

THERE IS NO BUS DRIVER!!!!

There are 7 girls in a bus.

Each girl has 7 backpacks.

In each backpack, there are 7 big cats.

For every big cat there are 7 little cats.

 

Question: How many legs are there in the bus?

 

 

Those that figure it out will get a cookie from me via FedEx :smiling2:

I have a degree in math, so does that mean I'm disqualified?

 

 

7 girls = 14 legs so far

7 backpacks * 7 girls = 49 backpacks

7 big cats per backpack = 343 big cats, 343 x 4 = 1372 legs, + 14 for the girls = 1386 legs so far.

343 big cats, with 7 little cats per big cat means 343 * 7 = 2401 little cats.

2401 * 4 = 9604 little cat legs

9604 + 1386 = 10990 legs in total.

If the girls are the only ones actually on the bus 14

if they have all their backpacks then 854 legs

if the 7 cats to every big cat are also on the bus then 5894 legs

and if we need to count the legs of the chairs in the bus then there's not sufficient information.

Am I smarter than a 5th grader?

No I am not. I think I missed a 7 or 7 7's.

7 girls with 7 backpacks makes

49 backpacks...

49 backpacks * 7 cats in each = 383 cats..

383 cats have 4 legs each.. so that is 1372. 7 girls have 2 legs each, so thats another 14..

 

So 1386 legs. Was it really that hard?

 

Also, it's "Are you smarter than a 5th grader?"

I got 10990 too. Let's see if the formatting from my spreadsheet worked out (edit: nope!).

 

------girls--backpacks--big cats--little cats

--------7--------49---------343------2401---

legs--14-------------------1372-----9604----

 

total: 10990 legs

383 cats have 7 little cats for a total of 2681

2681 cats have 4 legs each.. so that is 10724 legs. 7 girls have 2 legs each, so thats another 14..

 

10738 legs total. Where did I go wrong??

Wait wait wait...

 

What are the girls doing on a bus with no driver in the first place?!

 

Trick question! Without a driver, they can't get on the bus! The driver is the only one who can actually open the door.

 

Owned.

Unfortunately I will protest...the bus has 4 legs for each bench; a standard school bus (I'm a teacher) has 21 benches x 4 legs each, plus 2 front legs from driver's chair (no back legs...)

 

So, did Dark really get it right?

Yep, there are only girls, backpacks, little and big cats on the bus.
