Why are you dividing by two?

@Op
I did all in a few seconds.
Too cheap.
Let d ball=x
D bat cost 1 more than d ball: bat= 1+x
Total bat + ball=1.1
I.e x+1+x=1.1
2x+1=1.1
2x=1.1-1
x=0.1/2
x=ball=0.05

I divided the remainder into two so as to have equal values. Subtracting equal values of a number gives zero, thereby leaving us with a difference of 1.

Fancy yourself as a bit of a brainbox? While these three questions might seem easy enough to confirm yourself as being a genius, the answers might make you think again.
THREE questions separate you from being of average intelligence and full-blown brainbox – but are they as easy as they seem?
The Cognitive Reflection Test has been hailed as the world’s shortest IQ test because it features just three questions.
These three questions are much harder than they seem
Each one is designed to assess your abilities to identify a simple problem that might actually be harder than it first appears.
Not only do boffins claim that getting the right answer is a sign of genius, but also the time frame in which you come up with your solution.
Take the world's shortest IQ test

1. A bat and a ball cost N1.10 in total. The bat costs N1.00 more than the ball. How much does the ball cost?

2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?

3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size.If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Now you’ve had a crack at the questions, the chances are you answered 10kobo for question 1, 100 minutes for question 2 and 24 days for question 3.
If you did, you are wrong.

For Those still confused about no.1 here is the solution bat=b, a=ball total cost=t=,#1.10=110k EQN 1 a + b= 110 but b costs 100k more than a, b= (a +100) going back to EQN 1, a + (a + 100) = 110 2a + 100=110 2a = 110 - 100 2a = 10 a = 10/2 a = 5k

You people dividing that number one by 2 have zero idea of what you're doing. I think English language is your confusion.
