Their is one guy catching fish in a lake. While catching fish their are flamingos flying over the lake. The flamingo flying in front screams to the guy catching fish - All of us, plus all of us, plus the half of us, plus a quarter of us, plus you cathing the fish is 100.
How many flamingos flew over the lake???😕

36 + 36 + 18 + 9 + 1 = 100

Correct!

U know how many people dont even think of counting up to 100?
It is really strange

This is pretty basic algebra, no? I mean:

x + x + 1/2x + 1/4x + 1 = 100

11/4x = 99

11x = 396

x = 36

No?

Yeah, that's the way I would do it...not sure what he means by 'counting up'.

I don't understand that.

How do you get the 11/4x = 99 bit? Please explain.

Thanks.

x + x + 1/2x + 1/4x = 2x + 1/2x + 1/4x
= 8/4x + 2/4x + 1/4x
= 11/4x

11/4x + 1 = 100
11/4x = 99

Oh right....thank you.

I thought it meant 11/(4x).

My mistake.😳

Flamingos eat shimp 😛.

This is assuming we consider all taking flamingos honest, capable of counting to 100 and being terribly dull. :-)

2.75X + 1 = 100
solving it we get X= 36

thre are 36 flamingoes

i got a problem for every one let see how smart people are what two numbers do you add to give you 10 and multiply to give you 40

I'll give up after figuring out i needs to appear in the solution.

Never paid much attention to maths lectures by that point.

x+y=10 and x*y=40
Rearranging the first:
y=10-x
Substituting into the second:
x*(10-x)=40
Simplifying and leaving zero on one side:
-1*x^2 + 10*x - 40 = 0
A quick check of b^2 - 4*a*c gives a negative answer meaning on real solutions to this quadratic (square root of a negative number).
x= 5 (+-) 3.8729*i
Therefore there are no real numbers which satisfy your criteria.
