This one isn’t hard at all; the trick is to see how fast you can ‘grasp’ the problem and answer it without putting your pen down to paper!
In a certain town, four per cent of the inhabitants are one-legged and half of the others go barefoot. How many shoes are necessary?
.52 times the number of people in the town
1 per inhabitant
Same number as the number of inhabitants.
one-legged is 1.
half will times 2 back due to 2 feet.
So, back to square one.
100%
Image there are 100 people.
* Then 4 are with one leg and they need 1 shoe each. -> 4 shoes
* Of the other 96, 48 go barefoot and don’t need shoes. The other 48 need 2 shoes. -> 48*2 = 96 shoes
So 100 shoes necessary for 100 people. So 1 shoe per person.
The number of shoes needed is the same as the number of people living in the town.
Do the one-legged inhabitants wear shoes? Assume yes.
By “How many shoes are necessary,” do you mean necessary for each person in town to be wearing their usual footwear simultaneously? Assume yes.
#shoes = #inhabitants
Any even-numbered percentage would work for this problem.
One leg needs half a pair, and half the others were 2 and half were none, so that means just about half!
Or at least that’s what the average folks would say that were around the 50th percentile.
The number of shoes is equal to the number of inhabitants.
It depends on how many inhabitants there are in the town…
To tell you the truth, I googled the puzzle.
As many as there are people.
Well without any pen or paper I’d say if we don’t have the population of the village we can’t guess how much shoes would be necessary given the case they all walk at the same time (4% of the village 1 legged, 48% 2 legged and using shoes and the other 48% walking barefoot).
However, even given the case we know how much villagers are in there, we must stay alert to a detail: Which leg do the 1 legged citizens have left? Should we only count the number of shoes necessary without any regards to the side they should fit in (As opposed to the fact that you have to buy the pair to get one)? Should we consider you have to buy a pair to get one?
What about another fact: Will these people ever walk all together and need their shoes or can we consider they will share some shoes (given they can wear the same size)?
I think I’m overthinking it but it’s fun to see how it can get complicated if we overdo it.
No, I don’t have any clear answer, except (4% of the population * 1 + 48% * 2) shoes.
One shoe for each person in the town.
As many shoes as people… I did think about percentages for about a minute before realizing everything evened out.
The average number of shoes per person is 1, so you need half as many shoes as people.
The number of the shoes needed is equal to the number of the inhabitants.
the number of shoes required is equivalent to the number of inhabitants.
this one is soooo simple, think shoes ARENT a nessecity, you are able to walk around barefoot you know. The only thing the one legged people need is a crutch or a wheelchair!!!
First we let the number of inhabitants = 500
then we times .4 times that. 4% of 500 is 200.
split that bad boy in half.
We know 1 foot each = 1 shoe each.
and the others are barefoot.
100 were 1 shoes
100 were no shoes.
only 50 shoes would be necessary.
