this question is just meant to confuse you because regardless of the doubling its still 24 days.... what type of job would even ask this? bc its clearly not for a mathematician.

The answer is 47 days.

how? please explain.

"It doubles every day. It takes 48 days to fill the whole field. How many days does it take to fill half a field?"

The very last day is the day that it is completely full.

If the field doubles in size everyday, the day before the last day is when it would be half full.

It takes 48 days to be completely full.. which means on day 47, it is half full.

Day 46.. it would be a quarter full.

Day 45.. it would be an eighth full.

Day 44 etc..

wow, its a trick question then.... mathematically speaking i would like to think its 24 i mean i did the math on paper...its 24. But then there your kinds of people -_______________________-

Mathematically? No..

If day 48 is 100% full..

Day 47 is 50% full

Day 46 is 25% full

Day 45 is 12.5% full

...

...

...

Day 24 is 0.000000005960464477539063% or 5.960464477539063e-8 %

Let's try this with a smaller number of day.

There is a patch of lillies.

It doubles in size every day.

It wake 10 days to to fill the entire field with lillies.

How many days does it take to fill up half of the field?

Do the math and give me your answer.

5

No.

On day 5.. the field would be 3.125% full.

On day 9.. the field would be 50% full.

Can you explain to me how you're doing the math? what steps you're taking?
