- This geometry & Trigonometry video tutorial explains how to solve clock aptitude problems with shortcuts and tricks provided. It explains how to find the angle between the hands of a clock given time. It's important to understand that 12 hours represent 360 degrees and 1 hour represents 30 degrees. If the minute hand is at 12, the hour hand will be directly on the number it's pointing at. If the minute hand is on the 6, the hour hand will be in between two numbers. This video contains plenty of examples and practice problems.

Astronomy and cosmology has not been covered yet
this channel will definitely make me graduate this year 🙌🏻
Please marry me
this channel is the only reason I'm passing math
He is the best solver of Clock problems...he simplifies them till you see them as simple as water
i have no idea what situation i'd be in that requires me find the angle between the hands of a clock, but my test does so thank you for being so easy to follow
usually asked in finance related job interviews
I need it for designing an analog alarm clock on a ST7735 LCD display
Thank you for this lesson! I have a test tomorrow about this and had no clue how to solve one of these problems. I sent it to my friend who also was confused too and he too knows how to solve them now.
MR. Organic Chemistry Tutor thank you for this wonderful and well-known video on Clock Tricks.
In the last sol. It must be taken as 6 hrs as 12 to 5 = 5hrs & 11 to 12 is 1 hr more. So (5+1) hr + ( 25mins)
= 6hrs 25mins
= 30°×6 + 12.5°
=180°+12.5°
=192.5° [ solution ]
Anyways nice explanation! Keep trying!
Yea exactly, it'd be 6 hrs. 👍
You forgot one thing it's not 12.5 for the other side
It's (7/12)*30=7*5/2=35/2=17.5
He is right actually because he is finding the shortest angle
Thank you man it was a great help my mom was about to murder me you saved my life and i always remember you as my savior
yes he's a life saver
When I got the last question right, I knew that this is going to be my favourite video.
Can you please make more aptitude test style videos! Thank you so much and i really appreciate your efforts you put into your videos and increasing peoples intelligence free of charge!
I was confused last night but I watched your video then I had done the answer was correct thanks man.I need more.....👌👍👍👍👍👍👍👍👍👍😎😎😎
Thank you sir for this amazing Playlist. I am understanding everything. Thank you Very much.
Really amazing. Great math teacher ever... You made it easy thanks a lot...
Thanx so much you helped me a lot!
There is an epic formula to find this VERY EASILY: 30H - (11/2)M. Where H is the hour, and M is the minute. It always works.
It will be (11m/2) -30h
How did you deduct this formula, or where did you see it?
i honestly dont remember, but i got it from youtube.@@Mathematical-Mind
Not always
@@emmanuelboakyechemistrycla5071 It does always work. It’s a trick taught in competition math.
Thank you soo much i love you you made it easier some people just make it so complicated thank you ❤
Great work mate simple and detail
thanks a lot it helped me understand the concept so easily ,you're very good
Best teacher ever
My fav channel, thank you so much.
I don't think so.. I ever going to forget this.. tqsm
a magic formula for all clock problems :
m = (phi +/- theta)(2/11)
where m = minutes
phi = angle from min hand to hour hand
theta = angle from min hand to hour hand after m passed
The hands of the clock point to the 12 hours a day. When they signal 6 pm the number of times they will have formed An angle of 90 ° is?
He's so gifted I he makes maths fun
the only way to help this guy back is to watch the ads that popping out on his video and I'm going to write this comment to all of his video for you to know you can help him back by just watching his ads
Thank you for this video! I recently took a practice high school entrance exam, and on the maths paper there was a question that involved this; and I got stuck on it so I guessed, but thanks to your video I now understand it.Keep up the good work!😄
How many times in a day will the hour hand and the minute hand be at 30 degrees to each other?
22times in 12 hrs and 44 times in 24 hrs
Thank you for such a quick and nice video
Hi sir, can you release some hard question clock problems?
This is easy to understand. Thank you
Thx for the tip it helped in my exam
Thank You So Much!!
sir may i ask what calculator should i use this i.not good in decimal like 0.25 in convert to 1/4
u saved my life
Is it possible to calculate the angle between the hour hand and second hand, or minute hand and second hand?
Great video, very interesting and well done.
so u r using the minute hand value to determine where is the hour hand or the fraction of hour hand...but how to determine the location of minute hand if minutes' hand is not multiple of 5? how to find the fraction of the location of minute hand in case, as for eg, 52 min?
Thanks so much for helping in my exam
You are interested guy, I was very worried about one question whole day in this topic after seeing your video I catch every theory behind that question
BIG THANKS SIR
Thanks sir i understand now
Thank you
Great, dude!
Thankyou very much Sir!!!
Theta = (11M - 60H) over 2.. Try this shortcut. M = minutes, H = Hours
For all it won't workout
@@sowmya16390 nope it does, just apply some common sense
@@runfromlife6953 please apply ur formula for 10.52 with common sense
@@sowmya16390 Yes, It does and 10:52 would be 14 degrees
@@sowmya16390 it works even with this formula | 30H - 11/2M |
H = hour
M = minute
answer will be always positive since it's absolute value same as the former equation given.
¡Muchas gracias!
Thank you so much for explaining it
I love your voice, it's like you're talking with closing your nose with your finger :D
U have been always the most helpful youtuber in the youtube industry for mehhh
Love love love ❤️ Thank you 🙏
Nice explanation bro now I'm able to understand
Thank you sir 🙏🏻
TY for this video. :)
Thank you TOCT
Thank U very much
How do you know which side of the angle you do? At 8:58, I got 147.5 because I calculated the other angle. Could someone please explain how to determine which angle to solve for? Do I just start at the hour hand and go clockwise to the minute?
Usually it is the smaller angle is calculating
Thank you sir❤️❤️
Thanks sir..
Please do more aptitude test stuff!
thank you thank you thank you!
One clock with long sec hand while other clock have short sec hand which will move faster ?
Why do we substract 1 from 1/4 in the example 3 ..??
ummm im confused the book says that if its in clockwise rotation the degree should be in negative. but why is it 165degrees not -165degrees?...can u please answer HUHU
Thank you man......now it's clear to me.....thnx a lot
Thanq sir its very nice video..... N really helped alot
Amazing 🤩
How do i find the angle of 11:47 without using 30H-11/2 formula?
Best teacher thanks sir
thank you so much , now its all clear to me
Beautifully and crisply explained.
Thanks.. so much👌
Sivaprasad S mmmm it could have been better
@@electro_yellow9295 definitely a good approach
Thanks for learning us math know at school I going learn this
Best video ever 👍👍👍👍👍
nice and polite explanations
Clear explanation..
Practical approach sir
I am grateful to you
Are you from
0= (60-M)/2 + N(30) where M is minute and N is number on clock
What do you mean by number on Clock? Do you mean the hour?
The first qstn. that reads the angle between the minute hand and the hour hand will be 195°
What will be the angle between 5:27 ?
Thx man i have sea next year and this is helping me thx for da help man
And this, folks, is what led to the invention of the digital clock!
lol
I saw this comment that provided a formula to do the math in shortcut. Actually, it was wrong. Yall should use the formula:
| (60H - 11M)/2 |
here, if angle resulted is more than 180, then subtract that angle from 360° till it is below 180°
Nicely explained👌👌
Thanks you are the best
Thanks for this video now i understand how to get the degrees 😊
Thank You!
Gratitude for this conducive lesson.
The 3rd qstn that reads 11:15 the angle between will be 247.5° and the angle outside will be 112.5°
Please recheck and then submit.
Great explanation! I tried to do the exercises before I went through the video....very easy!
If you need a quick formula use this formula ((11y/2)-30x) where y=(minutes) and x=(hours)
I need this for a programming problem lol.
thank you 💕💕
Good trick
LAST PROBLEM ANS IS 197.5
yea
What will be the angle made by the hands of the clock at 3:55? Will it be 212.5 ? Can it be greater than 180?
3:55
Minute hand points at 11
Hour hand points essentially at 4
55/60 = 11/12
11/12 * 6*5 + 5*30 = 11/2 * 5 + 5*30
22.5+150=172.5
I learned a lot fro you
Thank for helping me 5:50
what if your minutes is in 7 or 23 or 34 or 42 or 58
My fucking professor didn’t even go over this in his lecture but I got it’s on the homework section. You’re a goat
Don’t swear
What if we included seconds
i thought the hour hand moves x/12 in every distance of minute hand moves.
