Cortana2:
You've almost nailed a job and then the interviewer placed on your table a white paper containing the following...

Legend has it that the inventor of the game called chess was told to name his own reward. His reply was along this lines.

Imagine a chess board.

Suppose one grain of corn is placed on the first square.
2 grains on the second
4 grains on the third,
8 grains on the fourth,

and so on until you get to the 64th square.

I would like as many grains of corn as the chess board now carries.

We were given just 5 minutes to do this...

EHI9ICE:



To you madam,I say 'well done'



And for the records(as pathetic as it may sound), I hate Mathematics.

Ohkay, nor be say i hate maths...I nor just gree know am. I pray to give birth to children,in future who are mathematics geniuses.

IAmOged:

this is the right answer....

Ifeshyne:
This is a geometric progression (g.p) with ratio = 2, a = 1 (first number) and n = 64.
we use formula for sum of a geometric progression which is s = a(1-r^n)/1-r


After substituting the values, Final answer has to be in standard form if calculators are not allowed
Something like 2^64 - 1 or even just 2^64

Ifeshyne:


Thanks, its never to late to know and learn maths. Matter of fact i was clueless in maths all through my junior secondary school days, it was my Maths teacher in ss2 and ss3 Mr Livingstone (God bless him wherever he is) that helped me start deciphering the subject. since then, my interest in maths has been heightened.

Icecomrade:

I just hate mathematics.

It is just there to test IQ, nothing more.

hiss

Apina:

Is mathematics now the standard for testing ones IQ?

olumose001:
all of you guys are wrong.. its actually sum of nth term of a geometric progression .. you'll end up having something like 2^63+2^62+2^61............ +2^1... but you could save yourself d trouble by using formulae for finding sum of nth term

What's with the whole interest in corns and grains? If I were you, I would have asked the recruiter if he was a fowl in his previous life.

pinkyruledworld:
I dont even understand

gaffig:

It is not correct, there is a little Kinkinli mistake in the formula

MRBODMAS:


show me snapshot of this numbers on your calculator. La copy la paste.
