You have a pan of water, pan A, it's temp is 50Celsuis. The milk in the adjacent pan, pan B, is 10% hotter. What is the temperature of the milk?

Salmotrutta Fri 06-Jun-14 19:13:42

55 degrees?

Salmotrutta Fri 06-Jun-14 19:14:47

Arrrrgh - I just made a schoolgirl error! grin

I won't spoil it for anyone else...

owlbegoing Fri 06-Jun-14 19:25:28

I'd have said 55 degrees too sad

CorusKate Fri 06-Jun-14 19:27:25

82 degrees Celsius?

owlbegoing Fri 06-Jun-14 19:29:24

OK so I think I know what the problem is smile

Salmotrutta Fri 06-Jun-14 19:31:12

Re-thinking this I actually now believe I'm correct.

Lewisfan Fri 06-Jun-14 19:32:39

no idea!

10 5 's in 50. 55.

Going to be 73.5 isn't it....?

Mull Fri 06-Jun-14 19:32:57

I haven't got a scooby! Why wouldn't it be 55?

Is not turned to butter by then?

aufweidersehenpet Fri 06-Jun-14 19:33:36

I don't think that you can work this out - as heat isn't the same as temperature.

Fridaybrainteaser Fri 06-Jun-14 19:33:56

Ooh. One of you is very close indeed.

Or cream?! Or something like that!!

ManWithNoName Fri 06-Jun-14 19:35:22

Its 55 degrees - undoubtedly this is a schoolboy error which is why I only got a B at O Level.

Mind you they were proper hard exams back then so that's like an A* now wink.

Degrees c doesn't start at absolute 0? So you need to allow for that in the calculation?

Salmotrutta Fri 06-Jun-14 19:36:45

Gaaaaah!

TortoiseUpATreeAgain Fri 06-Jun-14 19:36:59

Maybe 82.3 degrees C?

CorusKate Fri 06-Jun-14 19:37:20

I just did it in Kelvin and converted back. confused If it's not right then I've misunderstood the question or got my sums wrong somewhere.

CorusKate Fri 06-Jun-14 19:38:21

I gave my answer to the same number of decimal places as the figures in the original question as I was taught by my GCSE teacher. smile

CarCiKoTab Fri 06-Jun-14 19:39:51

55 or 60?

depends whether it's 10% of 100 or 10% of 50.

TortoiseUpATreeAgain Fri 06-Jun-14 19:39:57

Ah, you see I did O-level and they taught us to be precise... grin

SantanaLopez Fri 06-Jun-14 19:40:56

62.4 degrees celcius?

CorusKate Fri 06-Jun-14 19:42:18

grin Tortoise

CorusKate Fri 06-Jun-14 19:45:53

82.315 Celsius it is then, Torty. wink
