Your free RU-vid videos greatly help to the poor students like me who are not able to purchase your course.. Thank you

सच ही कहा है कबीर ने अधजल गगरी छलकत जाए

वाह सर क्या ट्रिक बताते हो हलवा के जैसे लगती है 🙏👍❤❤

900/L.c.m of 2,3,5 L.c.m of 2,3,5=30 900/30=30

Abhinav sir ne 5 saal phle ye method btaya tha❤

Sir ji aap best hai , mja aata hai aapse padh ke , mai pahle maths se darta tha aapse padhne ke baad aaj maths bnane me sabse jyada mja aata hai ❤️❤️😍😍😍🙏🙏

Eulers formula Ans is 240

Sir aapne bahut hi achchi method batayi hai,aapke tricks se mujhe upsc ke csat paper ke questions mein bhi kafi help milti hai.Lucky to have teachers like you.

form 1-100 there are 26 no not divisible by 2,3 and 5 but by your method, the answer is 80/3 = 26.66 isko 26 bna dete h 0.66 kam form 1-200 there are 54 no not divisible by 2,3 and 5 but by your method, the answer is 160/3 = 53.33 isko 54 bna dete h 0.66 jayda kab kam krna h kab jayda kase pta kare ye bhi btana

Sir ji ek dum fantastic tricks aur concept hai

Sir ji 1से 900 के बीच 898 संख्याये होती हैं न कि 900

Feels like probability... Thank you for teaching this method sir.. never going to forget

Chordo sir tution..4jis jis number se divied jata he bo 2se vi jata he isliya 3,4,5 ka L.CM=60 or 3,4,5 ka average 4 so Ans 60×4=240

Find the number of numbers between 300 to 400 both included that are not divisible by 2 3 4 5

That is true only for prime number not composite

Vakai ye aajtak maine itna aasan tarika nhi padha❤

Awesome trick sir, thank u so much ❤❤

No Short Trick, Just Concept... WOW...

2,3,5 ke LCM se bhi solution ho gya tha ,

Sir,🙏🙏🙏🙏🙏 सर जी हर चीज का अंत होता है आपको टीचिंग नहीं छोड़ना है । लेकिन हर चीज का एक दूसरा तोड़ होता है। ❤❤❤❤❤

Ye trick aapse pahle ktc concept bala sir bata fiye hai😊

Sir u can also easly check divisibility rule 240 only divisible by all 2&3&5

श्रीमान 1 से 900 के बिच की संख्याकी बात हो रही हैं न कि 1 से 900 तक की संख्याओ की.. . 1 से 900 के बिच मे 898 संख्या होती है... अगर मै गलत हूँ तो pls समझाए...

Awesome sir. Nice use of probability

सर एक बार आप राकेश यादव सर से पढ लीजिए आपकी गणित और अच्छी हो जाएगी

It is ¢(phai) function already taught by raja sir from neon classes....and he has explained very well how it functions....

This will only work in the following conditions: 1. The LCM of 3 numbers should be their product 2. The chosen number should perfectly divide the 3 numbers. If (1) is not true, common divisors should be taken only once. If (2) is not true the problem should be first solved for up to highest number which perfectly divides the product of 3 numbers, and then the leftover numbers should be considered.

Wow Zabardast Sir ka Subscriber 5 din me 2M Complete hona chahiye 🎉🎉 Please Sir ka Support kijiye

Euler Totient Function And darn he gave a nice proof as well... Really cool short video

Utube University ke professor 😂😂

Wah aapne kitna easily kar diya🙆🙏🏻

Hlo sir isi type range divisibility topic pr alag se lecture bnado plz

Accurate solution😊

Thank you sir for this amazing method 🙏🙏

You are the best Guruji, please provide your telegram channel,PDF of all of your best tricks,Sir I wanted to join your Math classes ,How much it cost ,could you please tell me ,my request.

Best methods maza aa gaya Guru 🤟😂😂

धांसू सर गर्दा उड़ा रहे है और आप शॉर्ट रिल्स बना रहे है सर

Sir trick sahi hai but aap number wrong le liye hai 1to900 between 898 =239 is the right answer ✅

Mere pe kirpa kiya jay जय श्री राम🙏🙏🙏🙏🙏

1 se 900 ke beech mein 1 aur 900 count thode na honge

👍🏻👍🏻👍🏻

Sir smjh nahi aaya ki 1 aur 900 ke beech me to 898 hi sankhya aayengi ya 900 Smjh nahi aaya ,jaroor clear kare 🙏🙏

Wow Amazing 😍😍 tricks 🎉 Thank you so much 🙏🙏🙏 sir

Aditya ranjan sir aaisa tukka baji wala sart na lagaiye hum ❤

The numbers 900 and 1 should not be counted in calculating because the question has asked “in between “ answer will be D

Abhinay sharma aslo teach this mathod to his students.

Ajkal ke ssc ke teacher apne aap iitian aur mitian isro ke scientist samjha rahe hai

Very good 🔥🔥🔥

Sir plz que me specify to kiya kro ki ye composite k liye nhi lagegi .. koi trick batao uske sath uske drawbacks bhi bataya Karo ..ty

यदि काटने के बाद decimal me number आया तब कैसे ans confirm होगा

Super sir jii aap ne to aag lga di🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🤟💯

Aur bhi chota method- Lcm(2,3,5)= 30 Har 30 numbers me 8 digits bchegi Single line answer- 900x(8/30) Chd do ab sir teaching😂

Thx you sir ❤ bahut vadiya hai shotkat

Mera tukka correct ho gya 😂😂

Teacher koi bhi ho but Abhinay sir sab ka Baap h❤❤

1 से 10 तक ऐसी कितनी संख्याये जो 2 व 3 से नही कटती 10*1/2*2/3=10/3=3.333...😂😂😂😂😂 आप पढ़ाना कब छोड़ोगे अब ? गुरु जी रूल वो बताए जो हर जगह लागू हो या फिर पूरी तरह क्लियर करें कि कब क्या किया जाना है?

Etna esay solution, thank you sir ji ❤😊

3 saal pahle dusre teachers padha chuke hai ye😂

Concept clear in first time for this type of question❤❤❤

Really appreciation for AR sir🎉🎉🎉

Lcm of 2,4,5 =30 option me jjsme 30 ka bhaag jayega wo answer

Aditya Ranjan sir ; unique

Aaj jake ye bat samjh me aa gaya sir

Sir, Jai Ho 🙏

How many numbers between 1500 to 1600 are neither divisible by 5 no 11.? Is method sei koi karke dikhaye please. I am confused

But between 1 to 900 asked . And there are only 898 number between them🤔. 1 and 900 are not included 🤔

Kya Gajan ka trick btaye hai sir jiiii bahut badiya 🙏🙏🙏🙏🙏

1+2+3+4+5 = 15 900/15 Multiply by 4 ( 5 tak tha usse pahle waala no. Le lenge) 900/15×4 =240

Lajawab trick h sir

Ka matalab hum msc Krna chhod de Euler phi function btaye hai short method ka btaye hai 😂😂😂 but shi hai confidence hona chahiye sir

Agar option continuous pattern me ho tb ye shortest tarika kam nhi aaega aur jyadatar chance hai ki answer glt hi aae.

#PAWAN RAO sir ne ye sab 3 sal pahle hi padha diya tha...jo ap bolte ho ye maine banaya 😄

Concept is outstanding

Ulooo banaya notice that👇 Between 1 and 900= 848😂😂😂 Naki 1 to 900

Mere pass ese se bhi tagda concept h

Abhinay sir se Sikh lia 😅😅

Short trick se best hai concept. Kyuki Jo road ko acche se janta hai wahi road ka shortcut bhi janta hoga

Your best experience of teaching❤

Well done trick includes basic also🎉

1 से 1000 तक कितनी संख्याएँ, 2, 3 और 5 से भाज्य नहीं हैं? Ispe lagu hogi kya ya nahi

Bhut tagde guru ji

वाह सर जी मौज कर दीए ❤❤❤

Excellent Approach sir ji

how many numbers are there from 1 to 20 which are not divisible by 2,3 and 5. ( now apply trick )

Permutation and combination ka concept use huaa hai

are sir jahar bata diye ❤❤❤❤ isiliye apki video aa jati hai to mai sabar kar ke dekhta hu jab bhi aap ki video dekhta hu to kuch naya jarur sikhta hu ❤❤❤❤😊😊🎉🎉

None of these. Answer is 239 Question mein given hai between 1 and 900, to 900 ko nhi count kar sakte

Exactly best method 💯💯💯

Wah nice. Trick sir👌

Abhinay sir ne btaya solution aise 88 number system wale topic

Nice trick guru ji😊

GOT of maths respect sir 🫡

Aisa baat nahi hai sir ji ye method sk jha sir me ke raushan sir bhi bataiye hain

Wow thankyou sir jii aap hindi me bhi smjhaye ho

जबरदस्त sr❤

Amazing 👍👍👍👍

💯💯🙏🙏
