Angle = 30H - (11/2)M
Perfect
👌👌👌👌👌👌👌👌👌👌👌👌
And why should I remember this, if I can do this conceptually in same time.
Easy
@@NoOne-ky1er Substitution in formula is easier than doing everything like this. I need to crack NTSE and there is 100 questions for 2 hours so it's impossible without shortcut.
You should simplify the numbers in your calculations to make it easy. Like 13/2 instead of 39/ 6 in the first question
For tnpsc if we use this methods means "timeout go away." see if angle bn 6.30 means sum all 30 degree from 12 to 6 30+30+30+30+30+30=180+(30mins/2)=195-180=15
Why does that formulae not work in rest of the problems ??
Clock wise direction =| 11/2m-30H |
Anticlockwise= | 30H-11/2m |
For angle bw hour and minute hand😀
how to apply this??
Absolutely right
After that I am getting answer as 5:43⁷/¹¹....can you help me out please?

Angle = 30(hour)-5.5(minutes)
= 30(6)-5.5(30)
=180-165
=15°
Bro is this a trick...?
@@sanferico5578 yea
It's more simple
so easy 😍
Wow.. Thanks for sharing ❤
ma'am yours calender is good but your clock have some issues .Kindly solve that .............
your 'faithfully

Another way (6:30 pm)
Hour hand at 6
Minute hand at 30
To move to 30,minute hand needs to go 180°
In 1 minute the hour hand goes .5°
So just do 30*.5=15°
Therefore when the minute hand comes to 30,the hour hand goes away from minute hand in 15°
So angle between hour and minute hand at 6;30 is 15°
It is simple when you use in mind calculation.
Bhai apka knowledge toh kamal ka he
😂
I always use this method instead of formulae in video😊
Mam Plzz can u make other video for clock ,I can't get that what u teached
Formula method: 30(H)-11/2(M).... Now let's apply it. H stands for hour that is 6 and M stands for minutes that is 30... 30(6)-11/2(30) this gives u... 180-165=15...........
It fails if they asked to find right angle between 5:30pm and 6:00pm
@@kingmaker9082 I HAD SIMPLE FORMULA FOR THAT TAKE
55=60
2ND STEP(U ASKED 5 AND 6 CLOCK SO 5-3 = 2, 2*5=10) AND (5+3=8, 8*5=40)
THEN SOLVE IN 2 WAYS
1ST
55=60
10=X(CROSS AND FIND THE SOLUTION)
2ND
55=60
40=X(CROSS AND FIND THE SOLUTION)
Akka pls do more problems on angles. As one problem is difficult to understand. Pls do 2 problems.
12:06 why it was 600 it should be 60 right
Your teaching is superb.thank u.
Mam use shortcuts instead of lengthy process that helps to save time in cracking exams
Ur teaching is beautiful like you mam 😘
I like your teaching really u made me ro become NTSCE TOPPER MAM REALLY
cute face beautiful voice & awesome teaching.
Madam we can use the formula for all sum (A=30h-5.5m) ,why you didn't use that madam while I use that and get the answer with 4,5 simple steps madam ,but anyway thankyou so much madam
Madam make it a simple. Minute hand moves 6° every minute and hour hand moves 0.5° every minute so ultimate angle after one minute is 5.5°and calculate accordingly.
How bro can you explain this
@@SriRam-ce3hi suppose the question is- find the angle between minute and hour hand when its 4.30.
While calculating every consider the perfect timing like in this case-4.00. Now minute hand will travel 30 minutes which means it will travel 180 degree ( minute hand moves 6 degree for a minute, so 30*6=180). Now for every minute hour hand moves 0.5 degree. So after 30 minutes hour hand will move 30*0.5=15. Now we know angle between each digit of watch. In this case angle between 4&6 is 60 degree. So 60 minus 15=45 degree. This is the answer. This may look lengthy but try such examples with pen paper
@@SriRam-ce3hi or other method- after every minute both hands move 5.5 degree. So after 4.00 minute hand will move 30 minutes. So 30*5.5=165 degree (this means hour hand moved 180-165=15 degree). Again the angle between digit 4&6 is 60 degree. So 60-15=45 degree is the answer
Thanks a lot bro
Tell me mail id bro
congrats mam u made it more complex to understand
Madam your teaching way mind-blowing
How so cute u r like ur teaching style. . Dont take in wrong way.
Simp
So how should we take it ?
Huh?
As a joke.......🫣
Let there be safe environment for women
Tq madam, good class
Nicely, explained this concept thank you 😊
Hi pragati

@@jatrahul194 chup reh
Between 5o' clock and 6o' clock, How can we take the time as 4:40?
Mam for the first problem minute/2 gives the answer in fraction of seconds...
Can we do that for all similar questions?
Best video. I am very confident in this now. Thankyou
In first question as the time is in 1:5 ratio we can use the formula Minutes/2
It gives u 15
U can do this to every time which is in 1:5 ratio
And if the time given is in 1:4 ratio then Minutes should be multiplied by 2 that will give u the angle.
Can you make a video on calanders keeping the aptitude level to the level of iim mba .
Thank You!
Beat method: 6:30 means hour hand is between 6 and 7 so angle will be half of 30 so 15 degree
Very nice mam
In all videos on u tube one type of problem is MISSING.
Q1)A wall clock takes 10 seconds to strike 6. how much time it will take to strike 12 ?
Q2) a wall clock strike 12 and it takes 33 seconds to do so. how much time it will take to strike 4
Q1.22seconds
Q2.9 seconds
Have doubt.
When the min hand gains 15 mins, by that time hour hand would be somewhat forward. Then how could say that they are coincide?
Similarly to the right angle question?
Thank you for best explanation
While solving sum on the board..you cover all the area..i am not able to see the simplification process 😅
Formula for Angle btw clock hand is -
Angle = 60×H - 11×M is divide by 2
For eg : time 4 :20 then the angle is -
60×4 - 11× 20 is divide by 2 = 10 * degree
This is the short cut method 👍
S
bhaiiii laundaaa h tu bhagwan tera bhala krrreee
edit yours self its angle =30h-11xMdivided by 2
6 : 30
Just divide min by 2 i.e 30/2= 15
Then 6 and 30 are overlaping so 0 Degree.
0+15=15 degree
Nice
It's very useful...
Im Rohith from VIT vellore ...big fan of your teaching mam... was very useful watching your videos...i cleared my exams
Thank you so much ma'am this video was very helpful.
u r looking beautiful and ur teaching too
thanks maam, its a perfect video as per my search query
Madam in part 2 your hair became short why madam🤔
You have to use the formula of the hour she gave and find it out 😂😂
I can never seen a talented teacher like you
True
in question 2, it says at what time? so after 16 4/11 min, what time will it be?
Thankyou mam u are best
Superb 🎉🎉
Madam 1 kind request...pls dont hide the board while writing...
Mam last question ka answer 35 degree nhi hoga kya ....
Mne 30 H vle formula se nikala tha
Please upload the videos for time and work , combinations
Mam can you make a video on paper folding and cutting please
I love your style of teaching ❤
Very good 👍
2 ; 15 afternoon to 2 ; 35 afternoon upto different minutes how many degrees madam ?
please answer this4 me.a clock gains 4 mins after every six hrs.if it was set to read 9 am on monday what was the actual time on wednesday of the same week if the clock indicated 9 pm? thanks
Thank you so much
Mam aapki smile bahut aachi hai
Please explain deferent of degree,mils, minute calculation
Why mam not using the formulas 11M - 60H/2
mam your really so beautifull and pretty and your concept explanation is quite good
very well explained and all videos are thought me very easiest method,but the thing is in most of all videos u always stand covering the board completely while solving problem, so we are not able see the board properly, so try to stand beside board while solving.
Sure and thanks for following our videos
This was very helpful...thank you👍
In the first problem .. I. e 30 ÷ 2 = 15°
If hour and min hand lie on the same axis ..
last question ✍️No need of this much lengthy explaintion!!!
Firstly solve angle between hour hand and minute hand using formula
angle = 30H-(11/2m)
If angle < 180 then
subtract (360 - obtained angle )
Which will be reflex angle.
The question before the last can't we solve it using formula ???
What if angle >180 ??
@@mettuudaykiran2917 Just write it down, it's the answer.
Gud explanation Ishwariya .
Really good videos within short time , thanks mam
Most welcome 😊

Thanks for the video mam!!!
Angel=30(H)~11/2(M)
Shortcut of finding between angle
Thank you
Tq ,excellent
Tqq super 👏
Teaching is super mam,
Please give the tricks about reasoning problems also mam
Benoliya what is Angela s
Your teaching super medam
Love you mam
one can also solve type 2 problem by using relative speed concept.
Yes bro that is more efficient
(60H-11M)/2 ANGLE can be found with this formula happy to share........
Q)for 7.23hr angle ?
A) (60*7-11*23)/2=83.5degree
Ply try to uncover the board while you are teaching.
Super teaching
Per hr 30 degree..then at 6.30 it's haf tha 30 degree .. obviously 30/2= 15 simple
lv u...
In 24 hours,
Minutes and Hours hand coincides 22 times
Minutes and Seconds hand coincides 1438 times
Minutes and hours hand coincides every 65 minutes not 60 mins
Even logically without any formula u can do in just 2 steps.
Super
i love you madam💗
Excellent class
This method is quite lengthy
We can go to gjp clock problems
Can you show the short method?
I will give you formula
30*hour -11/2*min
very nicely explained
thanku so much ma'am
Keep watching
6:30 hr and mins are on same angle, isn’t it
great
30H-11/2M
This method is quite easier,....
Clearly understood thank you mam
Maam plz 🙏 slow i couldn't seem ur those are wrote
we can just use first method,like hour hand angle taking 3hours and say x min find its angle
2)find minute hand angle taking x minutes and both should meet means same angle covered by both hands.this is for better understanding
perfect girl
Mam your language is so beautiful or wonderful
Mam looks beautiful btw 😍
