For 6, there is a mathematical way to solve it. X = your current age Y = son's current age. Now it goes into a system of equations. Your current age is equal to 4 times son's current age. x = 4y AND Your current age plus twenty is equal to two times son's current age plus twenty. x + 20 = 2(y + 20) So the system of equations is: x = 4y x + 20 = 2(y + 20) Now solve. Substitute. 4y + 20 = 2(y + 20) 4y + 20 = 2y + 40 2y + 20 = 40 2y = 20 y = 10 Now that we have y, we can substitute it into an equation to solve for x. x = 4(10) x = 40 I chose the simple equation there, but both work. x + 20 = 2(10 + 20) x + 20 = 20 + 40 x + 20 = 60 x = 40
0:33 you only need 3 attempts, use 1 key on the first 2 doors, then use another key on the two doors that are not the answer. Worst case, you don’t unlock any door, but you’re only asking for how many attempts to tell which key unlocks which door
@@icedfan1104the answer in the video still isn’t the maximum though, 3 attempts each door (worst case scenario) means 9 attempts. Also, yes the minimum is 2, but that’s the best case scenario. If you’re lucky, you’ll only need 2 attempts to figure out which key unlocks which door, but you’re guaranteed to figure out which key unlocks which door using only 3 attempts.

@@pyro2404No correct answer would be 3 maximum, So what I did, I would put the 1st key into 2 doors, and then you would know the location of 1st key, then the 2nd key into one of the doors, so if it's wrong the 3rd key goes there.

0:33 You only need 5 attempts it doesn't say u need to use the key for each door u only have to find the correct key for the correct door. key one 3 attempts, key 2 two attempts, key 3 no attempts became there is only one door left over.
For the people that don't understand the sushi and salmon. One sushi and one salmon is 7 dollars right? Now 2 sushi and one salmon is 12 dollars. Here is the solution: l V So you take the 7 dollars from the one sushi and one salmon and the 12 dollars from the 2 sushi and one salmon Next, u need to subtract the 7 dollars and the 12 dollars, it will become like 12-7 So 12-7=5 right? So the sushi costs 5 dollars Now subtract 7 and 5 like this: 7-5 7-5=2 The 2 dollars is the salmon Check it out yourself by adding them👍🏼
A riddle there were 3 Brothers that inherited 17 camels from their father the youngest of them inherited one ninth of 17 camels the middle brother inherited one third of the 17camel and the oldest inherited half of the 17 camels And they were arguing about how much camel they should get and none of them wanted a half camel (they wanted full camels) so can you help them divide the17 camels Answers in the replies
"Math only sounds boring when you don't know how to do it in a fun way". Well, I don't know how. Then the post says "I promise you are going to love these tricky math riddles". Sorry, but no, I don't "love" them at all. I was not able to solve any of them (I stopped after four or five).
For 6, there is a mathematical way to solve it.
X = your current age
Y = son's current age.
Now it goes into a system of equations.
Your current age is equal to 4 times son's current age.
x = 4y
AND
Your current age plus twenty is equal to two times son's current age plus twenty.
x + 20 = 2(y + 20)
So the system of equations is:
x = 4y
x + 20 = 2(y + 20)
Now solve.
Substitute.
4y + 20 = 2(y + 20)
4y + 20 = 2y + 40
2y + 20 = 40
2y = 20
y = 10
Now that we have y, we can substitute it into an equation to solve for x.
x = 4(10)
x = 40
I chose the simple equation there, but both work.
x + 20 = 2(10 + 20)
x + 20 = 20 + 40
x + 20 = 60
x = 40
3:34 what about 285
yeah i was thinking about that
Since they are different colors, in this test it MUST be assumed that they are all different numbers, which means IT CAN ONLY BE 285.

10:05 I’m pretty sure in sequences, 1/2+1/4+1/8… does add up to 1. The ant DOES reach his house, we just won’t know when

Minimum :-
Try to open the 1st door from 1st key. "It opens"
Now Try to open the 2nd door from 2nd key. "It opens again"
Now we know that the 3rd key will be of 3 rd door only
Therefore , Ans=2
Maximum:-
The first two doors doesn't open with first key
So it is of the 3rd door
Now we open it
(3 attempts done)
The 1st door doesn't open from the 2nd key
So we know that it is of the 2nd door
Now we open it
(2 attempts done)
Therefore the 3rd key will be of 1 door
Now we will open it
(1 attempt done)
3+2+1=6

The salmon sushi in the thumpnail is 2 dollars.
And the other sushi is 5 dolla

I know
Nahh.. it's -2 dollars, while the other sushi 7 dollars 🗿
It took me literally 5 seconds to figure that out
$5 & $2 a roll..💯
7:29, you can take the matchstick from the 6 and put it on the top of the 4 behind the equal sign to make it 9 so 4+5 = 9
For the 1st riddle it's 3 since you have to do 2 to find the first and if u guess the 2nd u can tell which goes into which
Yeah, I was thinking same. Worst case is 3 attempts, you don't NEED to check every key if it unlocks the door or not, if you KNOW it should.

6:51 0 is not a useless ok because 0 's. Inventor is Sir Aryabhatta and Zero can be multiplied by a number to make it zero.Are you understand 😉
In the matchstick one we can also move a stick from 6 to make it 5 and pace it on 4 to make 9 so 6+4=4 will change to 5+4=9
x + y = 7
x = y - 7 | -y
y - 7 + 2y = 12 | plug in x
7 + y = 12 | cancel out
y = 12 - 7 | -7
y = 7
x = 7 - y
x = 7 - 7
x = 0

For puzzle 7, there are two correct answers! 141 and 285
TRUE BRO! I ALSO DID IT AND WAS CONFUSED!
I feel like 285 is the only correct answer as the Xs were different colours implying different numbers
Actually just 5 attempts in 1st question because the last key automatically matches to the last door.

7:14 you can also move the middle machstick of the number 6 so it turns into 0 so the the equation is 0 + 4 = 4
7:09 why not 5+4=9
