Si je bois la moitié de ma bouteille de 50 cl, puis je te la donne et tu bois la moitié du reste, puis tu me la rends et je bois la moitié de ce qu'il reste, etc. jusqu’à ce que la bouteille soit vide... Finalement quelles seront les quantités totales que
Slice the full process in steps: Step 1: he drinks 100, you 50 Step 2: he drinks 25, you 12.5 etc. At the end, he will have drunk 2 and you 1. Thus he drank 33.33 cl and you 16.66 cl
for any quantity, the first person gets 2/3, the other 1/3. Because of the 1/2. This could be proven with calculus, or it's pretty easy approximate in your head- you get 1/2 of 25, or 12.5, then the other person has 6.25, then you get 3.1, then they get 1.5, then you get .7. Stop there. You get 12.5 + 3.1 +0.7 or about 16.3 that's pretty obviously about 1/3 of 50. So the other tiny sips would get you there. Fun problem, actually
Person 1: Drinks 50/2, then 50/8, then 50/32 and so on. It's an infinite suite, the infinite summation gives 50/2*1/(3/4)=100/3 which is 33.33. Same reasoning for the other person works, but knowing the bottle is 50cl, he drinks 16.66cl.
Very disappointing overall experience. Bored panel, not particularly friendly atmosphere. At the water, climate, biodiversity unit panel is drinking water from single use plastic bottles and offering water (not tap water) in plastic cups. I thought it was a test but it was real. I also paid 18euros to offset the carbon footprint for my flight to Paris and panel was uninterested. 1. No introduction asked, no friendly warmup chat. 2. Start with 5-7min presentation that was asked beforehand 3. Abstract question about presentation and points which are insignificant but is one of the panelists’ pet subject? 4. Why did I apply for the job? 5. Any challanges a colleague of mine faced in the past, what advice did i give? 6. How do i prioritise tasks? 7. How would i go about organising an event including getting people on board for presentations? 8. Questions to them
