He was rubbing the board but was still speaking (he didn't even wasted a second, *he was neither fast nor slow😉*), shows how much he had worked on those things before coming on here. ... i totally appreciate ur work and am thankful. !☺ Coming here, onto ur channel was really far more worth than going anywhere....

[@k.sreenivasprasad6840]

[@hilorigarg4323]

with all due respect, it should be 3 days 11 hours and 20 minutes not 20 seconds .correct me if I'm wrong.

[@highdrocarbon]

The hour hand of the clock moves at twice the speed of a regular clock and the minute hand moves at one-fifth the regular speed. If this clock matched time with a regular clock at 1 pm, what is the actual time when this clock shows 9pm (Options - 1 am, 11pm, 6pm, 4am)

[@alvinaug3844]

u r giving very good questions

[@jhanvisharma7192]

Thanks a lot sir...keep doing the good work👍👍

[@kaushiknath4717]

Sir, as the time difference is 16/11 minutes in 64 minutes, shouldn't it be (16/11)÷64x24x60 = 32.72 minutes difference (by unitary method) in 24 hours?

[@tanmay07777]

Great Video Sir 👌🏻

[@sandygamer3566]

great sir

[@awesomesrish96]

Sir. In the martian clock question, shouldn't it be covering 720degrees in 18 hours?(Half day) Like for one full rotation our clock takes 12 hours and not 24 hours. Shouldn't this take 18 hours and not 36hours?

[@Examrace]

Consider this a digital clock and not analog clock

[@kshiteeshbijjula8000]

In the Martian clock question, they didn't state the format of the clock, if it's day and night format or not. But if you apply the same to our clock, our clock doesn't cover 360 degrees in 24 hrs. Instead in 12 hrs.

[@annamkrishna5222]

Good

[@rushikeshpatil9621]

Sir, how did you convert (250/3) hours in days I did calculation and got 3.46 days But confused about what to do with .46

[@drajayofficials]

The minute hand of a clock overtakes the hour hand at intervals of 66 minutes of the correct time. How much a day (24Hours) does the clock gain or lose?

[@sandeephooda5350]

It will lose

[@aforapple4975]

nice one

[@expose4915]

There are two clocks. The first clock is one minute late every 45minutes and the second clock is one minute early every 30minutes. At which times should the clocks be set at 9AM so that at midnight both clocks show the correct time? Solve this

[@vatsalshah5628]

Sir in example 2 1440/1450*29*60 is equal to 1728 not 1680

[@sujitasingh9861]

You're good

[@SuhasJaladi]

Hello sir firstly thanks for this good video. In the video at 16:54 you took 1/6 deg per min ffor Hours hand but i think it should be 1/3 deg per min.

[@Examrace]

Notice that angle around a martian point is 720 degrees

[@yashbansal1127]

In last ques. Cant we do... In 1 hr min. Lost = 20 In 4 hr min lost = 20*4 = 80min Actual time = 5 h 20 min + 4 h 9:20 am

[@praveen-puli]

they given that the incorrect clock shows 4 o clock.you have taken 4 o clock acccording to real clock

[@arjitaagrawal257]

sir at 11:13 you told there are 11 coincidences in 12 hours....how to find number of coincidences?????

[@-CantHurtMe-]

it is a common fact you have to learn it

[@richamishra4949]

Can you tell how did 250/3 become 3 days?

[@Examrace]

250/3 is in hours and then convert it to days.

[@ayushkhandelwal8155]

It's approximation

[@venkatagayathripoka5839]

@@Examrace I can't understand sir 250/3 =3days

[@tanyajain9241]

250/3 divided by 24

[@pavanbalaji134]

U will get 83.3 and then divid with 24

[@rishikachauhan4490]

good

Hi sir, pls give me solu of this... 1. रविवार दोपहर 12 बजे मेरी घड़ी 5 मिनट आगे थी तथा हमीद की बड़ी 6 मिनट मन्द थी। बुधवार शाम को 8 बजे पता चला कि मेरी घड़ी 1 मिनट मन्द तथा हमीद की घड़ी 3 मिनट तेज हो गई। बताइए मेरी तथा हमीद की घड़ियों ने कब समान समय बताया होगा?

How many times the hour hand is faster than minute hand of clock?? Plz described

[@meetjain8045]

5.5 deg/min

[@SachinKumar-zc2mu]

55 min

[@yashbansal1127]

In first ques. You only considered the extra time that inaccurate clock covers with respect to accurate clock.. But in second question you took total time extra time + normal time... Why? Shouldn't in first ques it be 180*60+59/4----> 180*60

[@vrs822]

When will they show correct time simultaneously?

[@-CantHurtMe-]

if a clock is behind a normal clock but is gaining time it will show correct time when it gains that time of which it is behind of the normal clock

[@alammd.samsul8424]

what clock computer clock!...amd.

[@GaneshKumar-ip3oj]

5+5+48/60.....how 54/5?????

[@-CantHurtMe-]

10+48/60=(taking LCM)(600+48)/60=648/60=324/30=108/10=54/5

[@pokalanaresh1313]

10+4/5
