Gatt Posted April 10, 2008 Posted April 10, 2008 This is a 5th grade math problem. it is not a trick question.. This is a real maths problem so don't say that a bus has no legs. The bus driver is not part of the equation. 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 on the bus? I'll post the answer Tomorrow (Hmm.. no suitable Prefix..)
Ryan Posted April 10, 2008 Posted April 10, 2008 Got this in an email a few weeks ago - devilish! I'll keep schtum for now.
Trojan Posted April 10, 2008 Posted April 10, 2008 Right, here goes: (7x7)+7 =56 Cats per bag 56x7 = 392 Cats per girl 392x7 = 2744 Total Cats 2744x4 = 10976 Cat Legs 10976+(2x7) = 10990 total legs
Gatt Posted April 10, 2008 Author Posted April 10, 2008 BTW: No giving clues as to whether anyone is right or wrong
Guest kerrymoralee9280 Posted April 10, 2008 Posted April 10, 2008 Does the RSPCA know these cats are being kept in rucksacks?
sycho666 Posted April 10, 2008 Posted April 10, 2008 actually your right I dont. I prefer badgers. Much more friendly.
Diello Posted April 10, 2008 Posted April 10, 2008 7 girls, 7 backpacks = 49 backpacks 49 x 7 big cats = 343 big cats 343 x 7 little cats = 2401 little cats (2401 + 343) * 4 legs = 10976 legs 7 girls, 2 legs = 14 legs 10976 + 14 = 10990 legs So 10,990 legs. (Course, you did say "How many legs are there on the bus", technically the cats legs aren't ON the bus, because they're in a backpack..., only the girls legs are... but since you said it wasn't a trick )
Elky Posted April 10, 2008 Posted April 10, 2008 (edited) I reckon 10990 Edit - unless they left their backpacks somewhere else! Edited April 10, 2008 by Elky
mark80 Posted April 10, 2008 Posted April 10, 2008 Yup i think 10990 too 224 legs in 1 Bag 224 x 7 bags x 7 girls = 10,976 10,976 + (7 girls x 2 legs) = 10,990 Go on then tell me im an idiot lol

tmcd35 Posted April 10, 2008 Posted April 10, 2008 I've not heard this one before, but heres my answers .... Excluding the bus driver, if none of the girls have feet on the chairs, or are one legged or anything like that... There are 14 legs on the bus, the rest are in the back packs?
MK-2 Posted April 10, 2008 Posted April 10, 2008 14 not including the driver. only the first line states that the girls are on the bus. the other lines just state what the girls have, not where it is. I wanted to be awkward
Elky Posted April 10, 2008 Posted April 10, 2008 This is a real maths problem so don't say that a bus has no legs. Doh ;-)
StewartKnight Posted April 10, 2008 Posted April 10, 2008 The answer has got to be 14 It says there are 7 girls on the bus. There is no mention of the seven girls actually having the backpacks with them on the bus.
rush_tech Posted April 10, 2008 Posted April 10, 2008 Doh ;-) somebody had to say it I thought I'd get in first:D
Michael Posted April 10, 2008 Posted April 10, 2008 I received this weeks ago. I believe its in an excel spreadsheet where you have to enter the correct answer. I never got it right and gave up in the end. A friend of mine's an accountant and probably better at numbers than me. I'll ask him
