While walking through a market on vacation, you notice a small stand selling cameras. A camera-and-case set is selling for £310. The seller tells you that the camera costs £300 more than the case itself and that the case costs the price of the set minus the cost of the camera.
You decide you'd rather wait on buying a camera and opt to just buy the case alone. You hand the seller a £100 bill and see his eyes light up.
How much change should you be getting back?
Remember, you have 3 hints!
I'M REALLY SORRY I'M WAY TOO DIM FOR THESE! I STRUGGLED WHEN I HAD A WHOLE BRAIN , NOW THERE ARE BITS MISSING I'VE GOT NO CHANCE!!
Get yourself a pen and paper, I believe in you 
I can't do them either...and end up feeling stupid... I know that others like these puzzles and find them useful so I plan to steer clear of these and leave them to those who can... and if the originator of the puzzles continue to make it clear in the post title then it will be easy enough for me to avoid feeling stupider 
YOU ARE DEFINITELY NOT STUPID!! MY BRAIN IS WIRED FOR WORDS SO I GO TO MAT-BAT EVEN THOUGH I NEVER GET THERE IN TIME TO ANSWER FIRST.
I LOVE LOOKING AT HIS BRILLIANT PICS.
Time for a hint....

This puzzle isn't math intensive, but there is a particularly tricky aspect to it that trips most people up.
The camera and case cost a total of $310 but differ in price by $300.
£95
If the set costs . . . . . . . . . . . . . . £310
& the camera costs . . . . . . . . . . £300
Then the case costs . . . . . . . . . . £ 10. . . . . . . surely ???
£90. As worked out by CAT but missing the final stage.
Pay with £100, case cost £10 so change = £90.
£90 change. I,promise I worked that out before I read the other comments :).
Time for one of my tagged stories. The only tagged word is WALKING so this is going to be very brief.

The answer is...£95!

Thanks, I hope everyone's clear why the answer was £95...I think most were fixated on the camera costing £300 when what was actually written was "the camera costs £300 more than...", an easy mistake to make. I love these math type puzzles, but I think I'll keep answers to myself from now on lol
Oh shucks been away for a few days and missed this one! Not good with numbers but I did manage to work it out tho 
Ok having re read this I didn't work it out cos I was wrong!
How can it be £95? I don't get it surely the case was £10 - otherwise it would be cheaper to buy them separately as it costs £5 extra for the set?! I'm lost.....
The camera and case are £310 total, right? And the camera is exactly £300 more than the case, right? The only combination that works is £5 for the case and £305 for the camera. The camera is exactly £300 more than the case (£5 + £300 = £305) and the two items total £310. £5 + £305 = £310.
Hhm thank you for explaining but I get it now!
I made my answer too early actually. I was thinking of the question more this morning and realised that it couldn't be a difference of £300 and £10.
