Agr kisi ko 18/5 & 5/18 mein se konsa kb multiply krna hai ye jaldi se sochne mein problem ho rhi hai to bs ye dhyan rakho ki agr speed m/sec mein given hai aur hme km/hr mein chahiye to speed ko 18/5 se multiply kr dena(kyuki chote se bde mein chahiye aur 18/5 bdi value hoti h 5/18 se) Aur speed agr km/hr se m/sec mein puchi hai to hme bde se chote mein convert krna hai mtlb 5/18 se multiply kr lena... Bde mein convert krna hai to 18/5 Chote mein convert krna ho to 5/18 Bdi value means- km/hr Choti value means- m/sec Hr, min, sec ,km,m jo bhi diya h dhyan se dekh kr krna kyuki 5/18 ya 18/5 sirf Km/hr & m/sec ke case m hi use hota h Dusre case m dusra fraction hoga to galti mt kr dena... Agr kisi ki thodi si bhi madad ho jae to thik hai nhi to mere to kaam aa hi rha h ye.😃

The answers of homework..... 1) Speed=distance/time =500/25 =20m/s =20×18/5 =72km/h is the answer of this question. 2) let the length of sabarmati Express be x meter. Case:1 Speed=dist/time =(162+x/18)m/s Case:2 speed=dist/time =(120+x)/15)m/s =162+x/18=120+x/15 =810+5x=720+6x =810-720=6x-5x =90=x i.e.x=90m is the length of sabarmati Express.
66. Distance =(250+250)m=500m Time=25sec Speed =? Speed =distance /time =(500m/25)×(18/5) [*multiply 18/5 to convert it into km/hour] =72km/h 67. Speed is same bcz here given is same train. .......(1) Let,length is =x We know, speed =distance /time In case of 1st station speed=(162+x)m/18sec .....(2) In 2nd station speed=(120+x)/15.....(3) So,due to same speed by equating equation (2) and (3) we get, [(162+x)/18]=[(120+x)/15] =>x=90m =length of train.
Let the speed of train be x Length of train =250m Length of platform =250m Time taken by train to cross a platform =25sec Speed of train =? S=D/T Distance covered by train to pass platform 250m+250m=50m X=500m/25sec = 20m/sec Change into km/hr 20×18/5 =72 km/hr
Q.66) speed = 500/25 x=20m/s Q.67) There will be two equations 18x= 162+length of train 15x=120+length of the train So x= 14 And when put in anyone equation we get, Length of the train= 99
Question no.66: Distance=250 m train and 250 m platform so total distance is 500 m time is 25 seconds so the speed of the train =distance/Time i.e 500/25*18/5= 72 km/hr option d is the correct answer.
Answer of Q.66 is 72 km/hr. Q.67 is 90 m.(in Q.67 takes only 7sec) Q.67 S=(162-120)/(18-15) = 14m/s then length + 120= 14×15 length = 90 m Or then length + 162= 14×18 length= 90 m.. 🙏🙏

Question no. 66 Length of railway = 250 '' '' platform = 250 🔰Because it is written in the question that the same length of both...... 🔺To crossing time ⌚= 25 sec. 🔸Speed = D/ T = 250 + 250 / 25 = 500/ 25 = 20 m/s 🛑 To change the m/s to km/h 🔹 Multiply with 18/ 5 🔯 20 * 18/5 = 72 km/ hr. 𝓐𝓷𝓼.
we multiply the answer in the 1st question with 18/5 so to convert the m/s to km per hour. the 1st question was confusing but if we assume that only the pole was moving and had to cover the distance of the train then it might seem easier
T=d/s Let distance of train be x and y is speed of train then The platform no1 distance 162 m second platform distance 120 m Y=162+x/18 ......equation first y=120+x/15....... equation second Putting the value of y in equation first equation second 162+x/18=120+x/15 By solving the answer obtained is 90 meter

Case:2 speed=dist/time
=(120+x)/15)m/s

Question no.66: Distance=250 m train and 250 m platform so total distance is 500 m time is 25 seconds so the speed of the train =distance/Time i.e 500/25*18/5= 72 km/hr option d is the correct answer.
Yes_bro.👍
Yes bro
Right❤
First answer---
S=D/T
=250+250/25×18/5
=72 km/h
Second answer---
Let the length of the train be x meters
18x+162=15x+120
15(x+162)=18(x+120)
x=90m.
Answer of Q.66 is 72 km/hr.
Q.67 is 90 m.(in Q.67 takes only 7sec)
Q.67
S=(162-120)/(18-15) = 14m/s
then
length + 120= 14×15
length = 90 m
Or
then
length + 162= 14×18
length= 90 m..

Answer of second HW que: 90m (Assuming train is running at same speed while crossing both platforms)
Bhai mujhe thoda samajh me nahi aa raha hai pls samjha do
Substract both distance 162-120=42
Then substract both time
18-15=3
Speed =distance/time
42/3=14m/s
120+x=15×14
120+x=210
X=210-120
X=90

Sir in 2nd question you should use 5/18 while converting 48km/h to m/s but you have used 18/5 which was a bit confusing...
Exactly...I am also getting confused with 2nd question🤔
Moza 🔥🔥🔥sir learning everything from you 😊👍🔥🔥
RESPECTED DEAR SIR,
Q. NO. 66 ANS 72km/h.
Q.NO. 67 ANS 90m.
Sir aap ki vedio bank ssc sabhi ke liye helpful ha
सर आपकी कोचिंग कहां है •••••उसे अपने बेटे को maths की कोचिंग आपके द्वारा ही करानी है ।
REALLY U R THE BEST
we multiply the answer in the 1st question with 18/5 so to convert the m/s to km per hour.
the 1st question was confusing but if we assume that only the pole was moving and had to cover the distance of the train then it might seem easier
Hey
What about the 2nd question ??
I think it's worng ..
Can u plz tell
@@sikhabehera5252 Yes hum bade unit ko chote unit mei convert kr rahe hain.....Like km/h into m/s , then 5/18 se multiply hoga
😅
72km/h
Hello sir gift nahi Chahiye bs job mil Jaye yahi sabse basa gift Hoga thank you sir
Shri Radhe Radhe🙏🙏🙏🙏
Inshallah you may get work hard is the key of success
T=d/s
Let distance of train be x and y is speed of train then
The platform no1 distance 162 m
second platform distance 120 m
Y=162+x/18 ......equation first
y=120+x/15....... equation second
Putting the value of y in equation first equation second
162+x/18=120+x/15
By solving the answer obtained is 90 meter
D.72km/h Correct Ans Explanation. Given=D=250 but Read the Question Carefully train crosses a platform of the same length so D=250+250=500 Time=25Sec Find Speed=? Solution:- Speed=Dist/Time. 250+250/25×18/5. 500/25×18/5. Calculate we get. 100/25×18. Calculate we get. 18×4=72
D= 250+250, t=25sec then speed will be s=d/t=500/25=20m/sec×18/5=72km/hr .

Homework Answers: 72km/hr, 90m
Kaise bhai
👍
great session sir, no one can teach like you... I was always afraid of these questions, but after watching this lesson, my doubts are clear.
yes soo true
😀
Ans .66 will be 72 km/h
Ans.67 will be 90 m
Thank you sir...A great way of teaching 💚
Thanks dear sir,
I would like to share my experience with this channel is that before that I always left the question regarding time, speed and length,and age related and so..... but after learning, I have passed written exam and finally solved the problem easily, which was difficult to me before that.
czcams.com/video/c5jQkBqwb1s/video.html
1st, 72 km/hr
2nd, 90 m
Am I right
Sir please aur high level ke questions v karaiye...for banking exams....And I love and appreciate your teaching methods 🙏
You Are Great Sir and I also agree with Megna , Plz High Level ke Questions bhi krwao ap
You are very good teacher
India needs teachers like you 😀🙏👍
72km/h is answer of 1st question and 90m is ans of 2nd question
Kaise... Nikal ke bta do kya kya krna hai 2nd wala
@@raviprakash5893
Let length of the train X .... Now while crossing every station speed to same rahegi.... Speed = Distance/time....
Now 1 St station ki lambai 162m and usko lagne Wala time 18 sec so speed= ( 162+X )/18 ...... equation 1
Now 2nd Station ki lambai 120m and cross Karne ko 15 sec lagate hai so
Speed= (120+X)/ 15..... Equation 2
But train ki speed to same hi hogi so equation 1= equation 2..... So X ki value hogi 90m
Hope it helps😊😊😊😊😊🙏🙏🙏🙏🙏
@@cherrycherry8688 thnku Sir...😊😊
@@raviprakash5893 wc😁
(162+x)÷18=(120+x)÷15
Evaluate value of x, this value of is length of train
Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is...............................
iske solve krn bhi
x=90
66 is very easy
67. Let the length of the train be x.
First platform speed calculation:-
S=D/T
S=162+X/18............................................(i)
Second platform speed calculation:-
S=D/T
S=120+x/15..........................................(ii)
Evaluating equation (i) and (ii)
162+x/18 = 120+x/15
We get the answer is 90m.
66:- 72km/h
67:- 90m
Sab clear ho gya Sir
Bahut badiya sir
thanku sir basic math jabar dasta padhate hai.....lekin sir exam may kaise question atae hai $ har topic ka short trick with question ans......wala video.....banaye....plz...sir
Sir ji coching chordi apka video dekhkr waha ka.pale ni padta or apka pad hay bhul nai pate mind m set hogya h sab formula pahle k b thanku sir
Answer of Que 66 is 72 km/h and Answer of Que 67 is 90 meter
bro ur very supportive ... god bless bro
Sir u r great and thanks to your whole dear sir team for making such a good video for students.... Thanks sir
(a) 72 km/h is the right answer
Sir GIFT ke jagah par apna aashirvad de dijiye
67.D=90. Solution. Given=T1=18 L1=162 T2=15 L2=120. Find train length. Train length=L1T2-L2T1/T1-T2. 162×15-120×18/18-15. 2430-2160/3. 270/3 so 90 is Correct ans
Train length=250
Cross by train =250
Total length =500
Formula T =D/S
500/25×(18÷5)
Ans=72
it is already in m/s so the ans will be 20

Sir , 20 km/ H will be the answere of first question ,and 90 m will be the answer of second question
Your answer is correct of first question i dont know why everyone is saying that 72 km\h
@@technicalgamer5141 tumhara answer galat h 72 km hoga
@@Gauravbabu636 bhai 18/5 se divide kroge na
@@technicalgamer5141 250+250=500*18/5=1800/25sec 1800/25=72km/h
Bcz the ansr is 20m/s not 20km/h..n if we convert 20m/s into km/h we wl get 72 km/h only
Km/hr ko m/s convert krna ho to 5/18
M/s ko km/hr convert krneko 18/5 se mutliply kre

Q no. 67.
Sol.
Let length of the train be x m
Speed of train,
x+162/18=x+120/15
x = 90 m
Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:
Consider one train as an stationary now we can imagine as the length of each train is x mtr
Time=36sec
Speed=46-36=10kph=10*5/18=25/9
Length of trains =x+x=2x
Length=speed*time
2x=25/9*36=100
2x=100
x=100/2=50
x=50
50 meter answer hoga
Not entire topic of distance, speed , time is covered.
Please make more videos on this topic which completely covers this.
If a 250m long train crosses a platform of the same length as that of the train in 25sec then the speed of the train is answer is 72km/h
72 Km/h
Thank you dear sir for your
