Higher than B
Where's Bikies option?
you talking price, height etc??
please engage brain before posting
No, it's easiest to understand with an example. 'A' (eg. 110) is 10% higher than 'B' (100). 10% lower than 'A' would then be 99 (100 would be 9.0909…% lower)
HSC getting to you?
"A Is 10% Higher than B, Does It Mean B Is 10% Lower than A?"
Therefore:
A = B + 10% x B
A = 1.10 x B
A/1.10 = BWith example A = 100:
A = 1.10 x B
100 = 1.10 x B
100/1.10 = B
B = 90.9090B therefore does not equal 10% lower than A (which would be precisely 90).
QED.
if A is 10% higher than B, what % is B lower than A?
Not enough. I'm after 15% minimum discount, more for cash.
A = 1.1B
B = A/1.1
B = 0.90909AIn % terms, B is lower by:
= (A-B)/A x 100%
= (1-0.90909)/1 x 100%
= 9.091%
It can be if you ask an accountant
Isn't a poll a rather roundabout way to get your maths homework done? :)
Fun side fact:
x% of y = y% of xExample: Finding 18% of 50 can also be calculated by doing 50% of 18. Both equal to 9.
Because A * B = B * A. Elementary, dear Watson.
Pretty much. It's obvious when you think about it, but not many would realise to do this.
interesting
What does this have to do with the price of fish?
Next step is the share market conundrum ;).
If I buy BHP at $20 and the shares go up $40, I make 100% profit. However I buy BHP for $40 and they go down to $20 I only make 50% loss!
Or alternatively, I buy at $40 and they go down to $20 … 50% loss. But, I need a 100% improvement to recover my money!
please solve this conundrum ..
If you post a simple maths problem on OzBargain, are you allowed to hand up any of the responses as your maths homework?
10% changes depending on the number
Depends what it is. A comparison between a percentage (eg 60% vs 70%) or ranking (eg 10th vs 11th) is different to an absolute comparison (eg $10 vs $11).
This issue applies to every single item with GST. B is basically 10/11 (ten elevenths) of A which means it's 1/11 (one eleventh) lower = 9.09091%
where's the 420 option?
how many people here thought it was "Yes" at first then after seeing the comments decided to hitchhike with the crowd and comment how ludicrous this question is?
A: <10
B: >10, <50
C: >50Depends if you're using Cashrewards.
Are you High?
