Underrated channel.quality content is stupendous.excellent sir.
U r doing amazing sir. These vedios are really helpful. U make each and every concept intresting and easy. Words can neither qualify nor quantify how helpful your vedios are. Your way of teaching is much much better than any other coaching institute. Thanks a lot for your help and guidance.
😲😲😲😱😱😱😱😱
What was your cat score
Distance travel by sound in 7 sec is equal to distance travel by tiger in 83 sec, so 332*7= s*83 , on solving u get s= 28sec.
in case of father and daughter the ratio which is asking is speed of F to D so it will 7: 1
exactly you are right brother..
same
Yes...rest all is fine
I really like Sir saying just sit back and enjoy
I kind of learnt that from the video
I love you sir ; i will crack cat 2023 just because of you!!!!!!!!!!!!
Who are for CAT 2024?
Is bar graph from DI also available like this? M not getting
meeee :3
✋
Me
Yeah yeah yeah
15:10 yo iam hoping my brain works like this in exam 😂
in tiger question we can do one thing more that distance covered by bullet will be 332*7=2324m now so speed of t is 2324/83=28m/s
😂wahi toh kiya hai😅
That tiger is hella quick!

You are the best sir. You are way off teaching is ingenious.🙌
Alternate for 1st question
Consider distance between school and home as 100 km
120 mins - 200 km
105 mins - x km
x= 175
Daughter Travelled = 25/2 = 12.5
Father travelled = 175/2 = 87.5
Ratio= 7:1
Daughter ki speed kese find kari
but how we can commper the time becz the doughter trevaled 67.5 mints (60 early and 7.5 mint after the usual time plz explain me
To be honest i feel the question related to tiger is an ambiguous one.. the initial distance between tiger and hunter is not mentioned.. it is not mentioned whether the tiger was already running at a speed or did it start running after hearing the first gunshot... Sir solved it with the assumption that initial distance between tiger and hunter is zero and tiger was at rest before hearing the first gunshot
If he had assumed that the distance is zero he would not take sound to reach in x second still this is quite confussing
first time 120 mins when daughter started moving 105 mins so effective time dec 15/120 = 1/8 now total effective inc in total speed(father+daughter) = 1/(8-1) = 1/7 inc in over all speed and this speed inc is because daughter started walking so daughter speed = 1/7 father speed = 1 so ratio of speed of D:F = 1/7:1 = 1:7 Ans
If we calculate the father daughter speed ratio by calculating distance ratio it will be quicker
Speed of father be x
Distance travelled by him on other days 120x
(2hrs =120 mins, distance =s*t)
That day he travelled 105mins
Distance travelled by father 105x
Distance travelled by daughter 120x-105x=15×
Ratio of distance 105/15=7:1
Ratio of speed = ratio of distance
Therefor father:daughter speed ratio =7:1
wild question :)
wild Question !!!!
Sir I love you and respect you less than this will be a dishonour.
For doubts in the first question, do not worry. Sir may have forgot in hurry. So, just reverse the time and speed ratios as it is asked for father:daughter. Nothing more to worry about.
Sir is correct because
1/7 of 7 and 1/1 of 7 means we get 7:1 only
@@sairevanthkumarpoojari6049 yes you're correct 💯
Done 👍🏻

@ravi sir ur teaching is awesome...and the humor which u create sometimes I love it :)
okay i'"" make tiger question easy in hindi
"pehla shot tiger ne sun lia aap us first case me jo 3.5 second ka delay aaya usko.last me hi add kro i.e total 7 seconds ka delay aaya tiger ko awaazz sunne me uske 2 reasons 1st kyuki tiger bhaag raha tha 2second kyuki tiger tk phunchne me speed ko bhi kuch diatance travel krna pada. Ab haam aese kreng3e ki
speed sound ka 332m/s hai aur sher ka speed x hai
and pehle shot ke baad mano sheer bhagta hi raha bhagta hi raha jab tk usne 2nd gun shot nai suna matmb 1st second se bhagna shuru kia aur 83 second tk bhagta hi raha. lekin 1st gunshot aur 2nd wale me 76 seconds ka delay tha mab hunter nee pehla shot agr 1st second pr chalaya phir usne 76second tk wait krke 76 second pr shot chalayaa aur uss gum shot ki awaaz ne 332 m/s ke saath 7 second me instantly wo distance cover kr lia jo sheer 83 second se bhaag bhaag kr krra thaa jabse usne pehla gun shot suna tha to
332 (speed sound) * 7s (sound ne jitna time lia) = x(speed tiger) * 83 s (jab tk sheer 1st shot sunne ke baad bhagta hi raha) to ye dono hai total diatance jo travel hua jo ki same hi rhega kyuki sheer me 83 second me utna kiaa distance jitna shot ne 332 m/s speed ke saath 7 second me kr lia to speed apka ayega sheer ka 28m/s
Sir, first question is to find the ratio of father to daughter so the ratio should be 7:1. You interchanged the ratio. Am I right?
No he took reverse ratio ie daughter to father

Tomorrow is the exam day and I am doing this TSD now 🥲🥲..
Congratulations 😅
What's your score brother
actually in first question we have to find speed means distance traveled should consider so with time 52.5:105 ? ,, but how we get distance saved 7.5:52.5
Wild wild fr🔥
Why meeting time time of father and daughter not taken as 4:45 ?
Still need answer?
It is to and fro
I have doubt in 2nd question please make it clear
What is the doubt?
Genius
Sir atleast how many days are required to cover all your videos of quants from the scrap
20 days
Your puns :P
For the hunter-tiger question, shouldn't doppler effect of sound be accounted in as well?
no
CAT hai bhai, JEE nai
i was thinking of using that very formula only!
the answer matched with the doppler formula , I solved it!
could you share the formula of doppler effect?
this is K.O to use of equation
how the meeting time is 4:52:30? if the father saves both side's travel time?
tele id de will explain there
Sir,i can understand the father and daughter,how we get 4.52.6 time...in question 1
60.00 - 7.5 = 52.5

can anyone makes clear regarding what que is actually asking [16min longer than other) in cyclist problem
Thank you, sir.

Thankyou sir
Distance constant in que 3 ?
Sir I am not able to understand how you calculated time for sound to travel D distance ,,like for Tiger it took 83 Sec then how you calculated the same for sound. Plz explain sir its very urgent
It took 76 sec to travel to the old place of the tiger, so it would take an extra 7 sec to travel to a new place of the tiger.
@@nagasumanth4442 that's a lot of damage
4:08 how u calculate the time 4 52 .5 min?
exactly daughter travels for 22.5 mins only i guess
@@garimajain8193 he saves 15 mint from the usual time means he saves 7.5 mints in going and 7.5 mints in returning means he reached to her daughter at 4:52.5 mint
Are these questions extra tough or is this the usual level of CAT?
Usual...😢

Quants Wizard
how will he save 7.5 in backward direction
because if she have not walked he would have travelled towards school and return in the same direction again so he saved 7.5 in backward too.
Thanku sir
Thankyou sir
For cycle one, the first method not understood. Can somebody explain pls

Yes
From where u r doing ur preparation
Wild because it contains tiger XD, I am in splits

Anyone understanding the Tiger question, please explain.
It's simple.
When the first bullet was shot. T was at a point at x time.
T started to run and heard the 2nd Bullet after 83 sec.(x+83)time.
IF , the tiger didn't run he would have heard it after 76sec(x+76).
BUT, the tiger ran.
The time tiger took to run BTW 2 point is 83sec.
Now the sound need to travel that much too.
83s-76s =7s.
D is constant.

TSD giving me PTSD 🙃
at least you started early 🙂
Ravi Sir I didn't get one thing that when tiger is T1 then he should hear the second sound (x+76+83) sec isn't it??
NO at T+76 seconds
NO because T to T1 is the common distance travelled by both tiger as well as the gun so it will be X+76 ONLY.
nai nai gunshot fire hi 76 secs ke baad kia mab 76 second tk silenece tha wo time jo koi jo marzi kre phor 76th s3cond pr 2nd shot chalaya.. tiger bhaagaa isliye ko usual se zada time lga distance cover krne me tiger ka
