Solving ANY Brain Teasers After This Video. For Real!

Brain Teasers are getting more and more popular these days in job interviews. We see them in Wall Street interviews, in Google interviews, and also in Consulting Cases.

See how Kim Tran, a former McKinsey, shows you the "magical" guide to solve ANY brain teasers.

Hope to see you in the next video!

[thanks]

Question #3:
I see most answers like postbox, mailbox, which confounded me as it is not mentioned in the question, aside letters meant as the written paper inside an envelope.

What I see from the question is:
Word #1: when
Word #2: combined
Q asking which of the 2 above hold the most letters.
ergo answer: combined

[muditanimje]

It's an electric train !
Father question : the father was a preist
Two words when combined : diction+aries or post+office or mail+box
2 3 = 2+3*2 = 10 similarly 9 7 = 144

[snapback]

9 7= 144. you add the 2 numbers. then, you multiply it by the first, which in this case is 9. 9 + 7 = 16 x 9 =  144

1) illusion question
Well... it is an electric train, so there is no steam blow.

2) draw-explained question
Father could also mean priest.

3) wording question
mailbox (figured it out by reading comments)

4) pattern or trend question
(9+7)*9=144

5) logical question
Tom (figured it out by looking up on your website)

6) letter trick question
4 scrambled eggs

[abhinabmohanty]

1.Its an Electrical Train so no steam
2.Father here refers to a priest, presumably...
3.I think the 2 letters might be Post -Office
4.(9+7)*9=144
5.i guess its most probably Tom.
6.Those are some scrambled eggs....

I hope i got most correct

[justineyambao]

1. it's an electric train
2. Priest?
3. Electronic mail (e-mail) because no one really uses the mail box anymore
4. 144
5. Tom took the apple
6. (four) scrambled eggs

I have to say I really really like your philosophy, Kim Tran . You just proved it! I learned Brain Teaser using your approach!

[CaseyStClair-hmjr]

Has no one considered "the alphabet" for the most letters.
The "father" could be a priest and/or their biological father. The information states a woman and "a" daughter, it does not say she is the daughter of the other woman;therefore they could be sisters and the man their biological father.

[Waaagh]

Everyone says the father is a priest which is probably the thought of the question, but it doesnt say that the woman is the daughters mother so the woman and the daughter can be siblings and thus they both say "hi father".

[beyzaaltin]

do they let us to use pen and paper while solving logical questions ?

[royladot]

you walk intoa room and see a bed..on the bed there are 3 dogs, 2 cats, a camel and 3 turtles, there are also 4 birds flyng above the bed pls answer

[YoungCub]

(2 + 2) x 1 = 4
(2 + 4) x 2 = 12
(4 + 12) x 3 = 48
(12 + 48) x 4 = 240...

5. Tom took the Apple:
1) Let's filter out Tom's statement from the equation, because if he is right, then Jim, Hank will be 100% liars; in addition, since Don's and Eddie's statements directly contradict each other, we need one of them to tell a lie as well. We cannot have 3 liars.
2) Now, we have one lie left. If Don's statement is correct, Eddie and one more boy must be lying. Therefore, Don is the other liar.
3) Since Eddie's statement is correct, and "Both are lying" is a false statement, the only option left is "Both Jim and Hank are saying the truth", which goes in line with the information that 3 boys ALWAYS adhere to the truth.
4) As a result, the thief is 100% not Eddie or Hank. Jim is truthful, thus, Tom is the thief.

[nadezdakaterinalasalazullo]

I guess it doesn't really make sense anymore to comment the answers since everybody has done that and most of the people got all of them right, but... At least I know I found the answers on my own. So...

1. No direction because being an electric train there is no steam;
2. The man is a priest or the woman and the daughter are sisters and he is the father of both;
3. Post office
4. (9+7)*9 = 144;
5. Tom took the apple
6. Scrambled eggs

Thanks for the video, entertaining and helpful!

[jmok]

kind of a different approach for two words question: Alpha + Bet = Alphabet

[prateekjain]

Thank you, your videos are really helpful :)

[dianewise]

what is the brain teaser for lang4uage

[anishagoyal]

Father refers to a priest..for the first question the direction of the train is already given as the cities are mentioned(I' not from the US so Im unaware of the geography :( )

9*(9+7)=144

Scrambled eggs:)

[kylele]

Agreed with the below comment, except:

Questions with most letter - I would say i.e "mostly" (because it contains m-o-s-t letters?)
Questions with two women say "Father" at the same time - Maybe his name is "Father" ? I dont know haha :)

Please tell me if my understanding is right - and thanks for the great video :) !

Ans:
1. Illusion Question -> electric train doesn't emit steam
2. Draw Explanation question -> Father refers to a priest. Also, like others have commented, "woman and a daughter" could actually be related to each other as sisters, wherein the woman could also be a daughter to the man walking in. So there seem to be 2 possible correct answers for this one!
3. Wording Question -> Post Office or Post Box
4. Pattern or Trend Question -> (9 + 7) * 9 (which is the first number) = 16 * 9 = 144
5. Logic Question -> Tom took the apple. If what Tom said is true then both Jim and Hank are lying and also one of Don and Eddie is lying. This would mean 3 people lying that we can't have. Hence what Tom said must be false and hence Tom is one of the liers. Next Don says that one of them is lying and the other is speaking the truth. If what Don says is true then we have one of Jim and Hank to be a lier and we already have established Tom as a lier, plus we would have Eddie as the third lier as he is contradicting Don. Hence, Don can't be saying the truth and he is the second lier. What Eddie says, clarifies the position that both Jim and Hank must be telling the truth and hence Tom and Don are the two liers. Since Eddie has established that both Jim and Hank or telling the truth, we can deduce that Tom had taken the apple.
6. Letter trick questions -> Scrambled eggs
