first time in my life i m able to solve question that in few second thankyou so much sir.... a like and share is very little thing u ask in front of this level of teaching

[@mrssneha7658]

Sir no words are enough to appreciate ur way of teaching.....m married girl n have a daughter also....so can't enroll in paid classes of ur.....but there is no difference I think in paid n free class of ur ....thanks alot sir.....u r true inspiration for me.......🙌

[@Ganesh-3131]

2:20:09 Once clarify this sir.... The question was A will pass B by and A's speed smaller than B's speed

[@itssupriyahere]

Alternative solution of 2:24:20 this question Let x be length of train Speed in both cases is same so we get this equation 2x/40 = x+1320/100 x = 330

[@CoCoBoo313]

2:00:11 Asked distance = tunnel's length = train's length Asked speed = car's speed = related speed of train and car if they're running in same direction So time would also be 30 seconds. That's it. (question could be solved without pen and paper.

[@ZhongxGaming]

kaushik sir aapki jai ho... mein yeh crash course 2025 mein dekh raha hu ... aapne itne easy way mein samjhaya hai ki ab toh maths bohot easy lagne laga hai... this year i will clear bank exams for sure.

[@classic524]

In the last question, we can get the speed of A by dividing the length of the train with the time. 140/7=20. 40% more than 28 (speed of B). No need to take the variable. Great class, sir. Thank you.

I never thought that I will be able to solve Trains problem so easily. I thought this is a very hard topic but after watching this video my perspective has changed. Thank you so much sir!! For a CLAT aspirant like me you are a saviour.

[@silverfox1754]

2:20:21 sir answer iska option wise sahi hai but answer galat aaya he (concept wise)... Train A train B ko cross nahi kar sakta kyuki train A ka speed train B k speed se kam he. P.S. : I loved this session. Plz aisa mat sochna ki main hate kar rha hun video/methods ko

Sir, I'm a paid student of a reputed coaching institute spread across in India. I didn't like their classes. They were focussing on traditional way of solving the questions using equations. I liked your way of teaching, simplicity, dedication and the straight forward approach of not beating around the bush. You are definitely a gem. If I get the exam which I'm looking for, I would come to odisha and take your blessing before joining the organisation.

[@dark_satirical3872]

Jaipur to Secundarabad wale question mein extra distance travelled =54 km. TRAIN B is faster by 30 km. so, 54/30=1.8 is the total time travelled. shortest way. similarly, distance find karne ke liye, 54/30*150=270 km km answer hoga. noone is smarter than Kaushik Mohanty, he also knows this. i am just saying that this approach will be fastest in this case.
