### There are three bags, one contains only red marbles, one contains only green marbles and the last contains both red and green. You do not know how many marbles are in each bag. Each of the bags is incorrectly labelled. How many times do you have to draw to figure out the correct labels of each bag?

5 Answers

1 Draw. Solution: If all bags are labelled incorrectly, there's only two possibilities: (Using R=Red Bag, G=Green Bag, M=Mixed Bag) Actual Order: R G M Possible Labels: G M R or M R G (All other labelling makes one bag correctly labelled, can't be) Draw 1 marble from the bag labelled "M". If it's green, you've drawn from the green bag. If it's red, you've drawn from the red bag. Looking at the two possible labelling's, you can identify the other 2 bags. Less

One draw

### How many street lights would you say there are in the UK?

Hi, please can you shed some light on the mathematical questions you had to do in 15 mins? Were they problem questions (with words and numbers) or just a load of sums you need to do fill in? I have an interview and am worried... I am numerically dyslexic (dyscalculia) so need to thoroughly practice before it!!! thank you Less

They are a mixture of questions. Some are just sums and others are written form, eg. Ane is 2 years younger than Dave, and Scott is double the age of Dave etc. they can be pretty wordy but I'm honestly not sure they are bothered about this section! There are plenty of examples online though :) Less

I wish everyone good luck at the maths tests etc. but seriously don't get too worried over interviews at TPP. As you can see from this website , they have come across to many many people as a deeply unprofessional and odd company who still havent learned how to treat either their interviewees or their staff with common courtesy. Notice that loads of people have had bad interview and employment experiences with them (see wikijob for further examples), but apart from one case they haven't even replied to the reviews to apologise. Take it from me, its a huge red flag when a company just ignores negative feedback like that and refuses to apologise. It shows a basic lack of respect for people as human beings, and you shouldn't be putting up with this sort of thing. Also, if its your first interview be aware that TPP is not representative of graduate employers in general, if you find you get treated in an odd, dismissive or rude way don't worry about it and try not to let it knock your confidence. Remember its not you, its them! Save your worries for a company who will actually treat you right. Remember there are 27+ one and two star employee reviews that have been written about this company (the majority of the reviews on this site), don't just ignore them! Less

### If you were in a room with three light switches, and you could not see out of the room and you could only leave the room once. The three corresponding light bulbs are in another room. How do you tell which light switches belong to which bulbs?

3 Answers

My answer to this is: Assign a value to each light switch (A,B,C) Start a timer for 3 minutes Flip switch A and B on After the 3 minutes is up, flip B off again. Go into the other room. The lighting bulb belongs to switch A The the other two light bulbs (one will be hot and one will be cold) The hot bulb belongs to switch B The cold bulb belongs to switch C. Less

(I mean you would put one resistor in series with each of the three switches, obviously; the greatest value resistor would result in the most dimming). Less

Assumptions: You have three inputs: X, Y, Z with two possible states (0,1). You have three outputs: A,B,C with two possible states (0,1). The inputs and outputs are independent of each other, but one input should be matched to one output. For example, if X --&gt; A, then X(1) --&gt; A(1). Note: we don't actually know whether the normal state of the switch is open or closed. For our purposes 0 is normal state, 1 is abnormal state. You have one chance to observe the outputs. You could flip one of the switches and observe, but this will only tell you about one of the connections and leave two unknowns. You could flip two switches, but this still leaves two unknowns. You could flip all three, but this leaves three unknowns. You could flip none of them, but that leaves three unknowns. Another possibility is to McGyver the light switches by placing three resistors of different values in series with the switch, verifying the switch is closed, and then observe the relative brightnesses of the bulbs. More creatively, you could use your one trip to leave the room to find the documentation and/or the persons responsible for this cruel experiment. I am sure this is wrong, but I was never a math or CS major. =D Less

Hey I did an assessment centre almost two weeks ago now and haven't heard anything yet - do you know if unsuccessful applicants are also told by phone? :) thanks! Less

Hey, remain patient as it took a couple of weeks for me to hear back. I was also told that they were still in the process of letting applicants know the outcome and that they still had over half the people to inform. I'm sure you will be contacted one way or another so fingers crossed! Less

Hi there, I had my assessment centre later than you on the 18th of August and have still not heard anything. Any idea if this is good or bad and when I should expect to hear back? Thanks in advance Less

### Q: Assume you want to get from city A to city B. There are three roads you can choose uniformly from. However only one road leads actually to city B, which takes 2 hours. The other two roads end up in city A again and both are 1 hour long. Given that you don&amp;#039;t know which road you took, If you return to city A (i.e. you have to choose uniformly a road again), what is the expected time to get to city B?

2 Answers

2.5 hours (if expected time is the same as expected value here)? If it's equally probable to choose right (2 hour) or wrong (1 hour) and then, finally, right (2 hour) route (i.e. total 3 hours), then the expected time is the mean (2+3)/2 = 2.5 hours Less

X=1/3*2+2/3*(X+1) → X=4h
