mam was in her own world while teaching in almost all videos
?
Your teaching is superb.thank u.
Thank you for best explanation
You should simplify the numbers in your calculations to make it easy. Like 13/2 instead of 39/ 6 in the first question
Why does that formulae not work in rest of the problems ??
I like your teaching really u made me ro become NTSCE TOPPER MAM REALLY
Best video. I am very confident in this now. Thankyou
Thank you so much ma'am this video was very helpful.
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.
Akka pls do more problems on angles. As one problem is difficult to understand. Pls do 2 problems.
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
thanks maam, its a perfect video as per my search query
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
😂
Can you make a video on calanders keeping the aptitude level to the level of iim mba .
Mam Plzz can u make other video for clock ,I can't get that what u teached
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.
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?
cute face beautiful voice & awesome teaching.
This was very helpful...thank you👍
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)
Nicely, explained this concept thank you 😊
Hi pragati
😎😎
@@jatrahul194 chup reh
Ur teaching is beautiful like you mam 😘
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 ❤
Madam your teaching way mind-blowing
Please upload the videos for time and work , combinations
Thank You!
Thank you so much
Thanks for the video mam!!!
It's very useful...
Gud explanation Ishwariya .
Your teaching super medam
Really good videos within short time , thanks mam
Most welcome 😊
Im Rohith from VIT vellore ...big fan of your teaching mam... was very useful watching your videos...i cleared my exams
Q. Solution:- 15° angles between the hour hand and the minute hand when the time is 6:30 clock.
Nice Explanation Mam🤗😌
Thank you mam
It helped a lot thank you mam

Mam can you make a video on paper folding and cutting please
one can also solve type 2 problem by using relative speed concept.
Yes bro that is more efficient
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?
Nice work 👌
Beat method: 6:30 means hour hand is between 6 and 7 so angle will be half of 30 so 15 degree
I love your style of teaching ❤
Very nice mam
Clearly understood thank you mam
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
Thankyou mam u are best
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
Tq ma'am I'm going to pass my exam
Use the same formula for entire problem (except one) of this video
That is ,
Angle = 30H-(11/2)M
And why should I remember this, if I can do this conceptually in same time.
@@NoOne-ky1er u could save some time ?
@@nihalashirin5201
Don't need to save time in CGL tier 1
yess broo...
very nicely explained
U are so beautiful mam😁🥰👍
Mam use shortcuts instead of lengthy process that helps to save time in cracking exams
Superb 🎉🎉
Thank you ma'am,it was really helpful.
Please explain deferent of degree,mils, minute calculation
Super teaching
Just like the way u r teaching , 💯👏 keep posting videos
Mm
Teaching is super mam,
Please give the tricks about reasoning problems also mam
Benoliya what is Angela s
u r looking beautiful and ur teaching too
Nice class mam 😍
mam your really so beautifull and pretty and your concept explanation is quite good
Please upload videos for combinations
Mam aapki smile bahut aachi hai
in question 2, it says at what time? so after 16 4/11 min, what time will it be?
Bhut umdaa madem ji
In the first problem .. I. e 30 ÷ 2 = 15°
If hour and min hand lie on the same axis ..
Very good 👍
Love you mam
Happy teachers day leswariya ji
Nice madam explanation is as good as you look.
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
thank youu
Super mam
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
Please make on one video of Average
Super
Thank youu
Excellent class
(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
ma'am yours calender is good but your clock have some issues .Kindly solve that .............
your 'faithfully
hari om bhatt
Even logically without any formula u can do in just 2 steps.
Mam for the first problem minute/2 gives the answer in fraction of seconds...
Can we do that for all similar questions?
Mam great
Thanks a lot mam ur teaching skills are good and your explanation is very clear and these topics are very useful mam thanks a lot 😘😘😘😘😘😘😘❤️
thnk u mam
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
Does tis topic come under verbal or logical reasoning
great
5:35 waqt badal diye jazbat badal diye
thanku so much ma'am
Keep watching
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.
I expect topics from data interpretation
nice lecture
Nice
Madam in part 2 your hair became short why madam🤔
good akka
Nice mam
Thanku Ma'am,it was great help...u teach 🙂
Glad to hear that
