sample questions for intro level business analyst type job (not quant but you have to have an intuitive grasp of numbers)

starting with the easiest:

there's a pond with lily pads on it. every day, the number of lily pads doubles. on the 40th day, the pond is completely covered. on which day is the pond half covered?

could be 38 too if question doesn't specify that the 40th day results in "just-barely" coverage.

1 + 99 = 100.

2 + 98 = 100.

and so on. so we end up with 49 pairs with a value of 100 each. 49 x 100 = 4900. We have 1 50 left over. 4950.

4950.

to find the sum of consecutive intgers, the formula is simple (i believe it was discovered by gauss). add the first and last integers in the sequence and then multiply that by half of the total numbers in the sequence. so here, it's 1+99=100. and then 100*49.5=4950

oh this is more elegant than mine, I just figured that there are pairs of numbers that will each equal to 100, starting with 1+99, 2+98, etc., but there will only be 49 of them because 50 does not appear twice. So 49x100, and then add the 50.

594

I sample the sum of the first eleven numbers in the series: 1+2+3+4+5+6+7+8+9+10+11 = 66.

From this sample, I can reasonably estimate that each sample of eleven numbers in the overall series sums up to 66, and the total number of samples of eleven numbers is 99/11 = 9. therefore the total sum for 9 samples would be 66*9 = 594 +/- 7.4 at 95% confidence

Imagine a 99 x 99 stack of unit area blocks. Then divide the stack in half by a diagonal line going top left to bottom right.

The question is equivalent to asking what is the total area of the blocks either entirely to the left of the line or cut by the line.

(99 x 99)/2 gives you the area to the left of the line but then you have to account for an extra 99 half-blocks for those blocks cut by the line, so:

(99 x 99)/2 + (99 x 0.5) = 4950

You first notice that B must equal 1 since it's the only number that can be carried to the thousands place when adding merely two numbers together. From there it flows fairly easily.

ABC=813

CBA=318

BBCB=1131

pretty simple once you realize that B has to be 1. if you are adding 2 3-digit numbers, the largest possible sum is 1998 (999+999). so B must be 1. C+A must equal 1, so the possible combinations are like 7, 4 or 8, 3, etc. i plugged in 8, 3 first and got the right answer.

sum of the first row is 5*11 (using the gauss formula above)

each row is n*(first row) where n is the value of the row digit

so 55 + 2*55 + ... + 10*55

iow, (1+2+...+10)*55 = 55^2

You are offered to play a game of chance. A fair coin is tossed repeatedly until you get the first tails, at which point the game ends and you get the prize. The prize "pot" starts at $1 and doubles each time you get heads. So for instance, if you get heads the first toss, the pot becomes $2. If you get heads again the second toss, the pot becomes $4. If you get heads the third time, the pot becomes $8. If the fourth toss gives you the tail of the coin, you win and take home the $8 prize.

Before you play, you must pay a fee to enter this game. The question is, what's the maximum amount you're willing to pay in order to play this game?

Got this one during my b-school interview:

You have a lamp that you need to set on a timer. You want it to come on for two periods daily: 5-8am and 5-8pm. You have an unlimited number of light timers that each can allow power to the lamp for one period (think: those cheap Ikea timers that would allow the light to be on for one period per day). You can run these timers in sequence.

How many of these timers would the lamp require, and each set to what period, so that it will be on for these two time periods during the day?

edit: 24 hour timers. Lamp has one cord going to a single outlet. Multiple timers would run in sequence.

Well, you could set a timer to be on from, say, 1am to midnight. And then set the second timer in sequence so no power gets to the lamp except from, say, 1-3pm. Then despite two timers, the lamp would only be on from 1-3pm.

this is a well known one

One hundred ants are dropped on a meter stick. Each ant is traveling either to the left or the right with constant speed 1 meter per minute. When two ants meet, they bounce off each other and reverse direction. When an ant reaches an end of the stick, it falls off.

At some point all the ants will have fallen off. The time at which this happens will depend on the initial configuration of the ants.

Question: over ALL possible initial configurations, what is the longest amount of time that you would need to wait to guarantee that the stick has no more ants?

Can we choose which direction each ant starts traveling? I suppose the longest version in that case would be a configuration with each ant 1/100 of a meter apart, but that seems like a giant pain in the ass to calculate.

the key to solving this problem is to understand that 2 ants hitting each other and turning around is the same thing as 2 ants passing right through each other. so all the bouncing back and forth is just a red herring - the maximmum time it takes for all ants the clear the stick is the same as the maximum time it would take one ant to clear the stick - 1 minute

A shopkeeper says she has two new baby beagles to show you, but she doesn't know whether they're male, female, or a pair.

You tell her that you want only a male, and she telephones the fellow who's giving them a bath.

"Is at least one a male?" she asks him. "Yes!" she informs you with a smile.

What is the probability that both beagles are male?

This is the way it was explained to me, but I find this suspect. You are treating it as though there are "positions" for the dogs. But as I see it, there is only one dog and the other dog, so there should really only be two cases

MF

MM

where the second spot represents "the other dog."

the dogs don't have positions, but they are distinct individuals. "is at least one male" is fulfilled by either one being male or by both being male.

your reasoning is correct for the question "is dog A male" but not for the question "is at least one of dog A or dog B male"

I understand that, but I disagree with the premise of assigning them "A" and "B"

Let's phrase the question another way -- you are going to a wedding, and at least one of the people getting married is male. Assuming homos and heteros are equally distributed, what is the probability of the couple being gay? The answer is 50%. There's no left and right, A and B, 1 and 2 slot, etc., you just have a man, and he is either marrying a man or a woman. 50%.

No you have 4 scenarios:

You've eliminated the FF wedding, but you have a 1/3 shot at dat MM

edit: If you know in advance that it is 1 man marrying either a man or a woman, then you are right. But if you are going in blind and ask someone "is atleast 1 partner a man", then the odds play out as I showed above.

With the wording of the problem, you assume that the person on the phone knows the sex of both puppies.

It's similar to the monty hall problem, where the fact that the host knows that he is showing you a losing door changes the odds vs if he were to show you a door at random and it happens to be a loser.

If he had only looked at one dog, and it happened to be a male, your numbers are correct.

the point is, each puppy has a 50/50 chance of being male or female. if you want to keep track of each puppy separately (which you need to to do the math correctly), you need to label them somehow. whether it's "A" and "B" or "X" and "Y" or "dicks" and "dongs" doesn't matter, but you need to keep track of both puppies separately.

Here's another way to think about it:

The guy on the phone is effectively saying "I have two puppies here, one to my right and one to my left, and at least one of them (the one I'm looking at) is male"

There are four possibilities now:

1) The one he is looking at, R, is male, and L is also male

2) The one he is looking at, L, is male, and R is also male

3) The one he is looking at, R, is male, and L is female

4) The one he is looking at, L, is male, and R is female

The odds of two males becomes 50%. I don't see why this is any more or less a reasonable way to interpret the problem than the standard answer.

You are on a rowboat in the middle of a large, perfectly circular lake. On the perimeter of the lake is a monster who wants to eat you, but fortunately, he can't swim. He can run (along the perimeter) exactly 4x as fast as you can row, and he will always run towards the closest bit of shore to your boat. If two paths take him to this location equally quickly, he will arbitrarily choose one. If you can touch shore even for a second without the monster already being upon you, you can escape. The monster can reverse direction instantaneously and you can turn your boat instantaneously. Suggest a strategy that will allow you to escape, and prove that it works

This is simple -- just row in a straight line to the furthest point from the monster (the point directly opposite the monster) when you start rowing. You will get there faster than him.

ok, i think i've got it.

my original idea was to paddle in a circle with a radius of r/2 (a circle inscribed so that r of the pond is its diameter). this had the virtue of forcing the monster to run towards a spot that you were moving away from. sadly, he only has to cover 3/2 pi r in the time you take to travel 1/2 pi r, so you still lose b/c of his speed advantage. (he only needs to be 3x as fast as you to arrive at the same moment).

this made me realize that the monster's speed advantage always allows him to catch you on an arced course whenever the distance you travel is that of a circle with arc >= 1/4r

so i think you win by 1) paddling in a circle with arc < r/4, which should allow you to get to a point where he is trailing the point your bow is pointing at, and then 2) go straight to the shore

do i get to be a janitor for quants with this answer

this is correct if you're saying what i think you're saying which is that you can spiral out until you reach a circle of radius 1/4r (at which point you can no longer outdistance him). then take off like a bandit to the opposite side of the shore from where he is

Yragle the pirate has 100 white pearls and 100 black pearls. The white pearls are worthless, the black pearls are priceless. He will let you distribute the pearls between two sacks, labeled "Heads" and "Tails." After you distribute the pearls, you flip a fair coin and choose a pearl at random from the corresponding sack. How should you distribute the pearls between the two sacks to maximize your odds of getting a black pearl?
