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

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

सच ही कहा है कबीर ने अधजल गगरी छलकत जाए

Abhinav sir ne 5 saal phle ye method btaya tha❤

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

That is true only for prime number not composite

Eulers formula Ans is 240

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

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.

Awesome trick sir, thank u so much ❤❤

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...

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

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

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

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.

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

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

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

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

Vakai ye aajtak maine itna aasan tarika nhi padha❤

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

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

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

Thank you sir for this amazing method 🙏🙏

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 ❤❤❤❤😊😊🎉🎉

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

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

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

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

Indias no1 teaching platform 🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹🌹..... With ranjan sir........ Hi this is. Pawan das from chittaranjan 💕💕💕💕💕💕

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

Utube University ke professor 😂😂

Well done trick includes basic also🎉

I am paid batch student of aditya ranjan har question main alag trick exam main trick nhi chltii basic chlta haii... Pehlae basic par achii command hooni chayae phir baad main aisii trick chltii hain...

Best methods maza aa gaya Guru 🤟😂😂

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

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

Wah aapne kitna easily kar diya🙆🙏🏻

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

Abhinay sharma aslo teach this mathod to his students.

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

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.

Abhinay sir se Sikh lia 😅😅

Very good 🔥🔥🔥

Thx you sir ❤ bahut vadiya hai shotkat

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

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?

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

Your best experience of teaching❤

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

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

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

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

Sir mene bahut teachers se math padha par exam me thodi bahut kam ayi par apse math padhke asa lag raha abhi kuch to karuga math me. Bas ek rqst h sir ab ye tcs Or ssc dono ne calculative math de rahe h pehle digital sum se solve hojata h par ab asa qstn de rahe jisme digital sum apply nahi ho payega to krupiya is calcutaion ki hal k liye koi trick jo ssc Or tcs k sawaalon pe magic hojaye to bahut sare candidates apke abhari rahege🙏 dil se thank u sir

Mera tukka correct ho gya 😂😂

Really appreciation for AR sir🎉🎉🎉

Awesome sir. Nice use of probability

Sir agar ans point mein aaraha hai toh kya hoga … like in between 1- 20 aise kitne numbers hai jo 2,3&5 se divisible nhi hai … toh same formula use karnese 80/15 = 5.33 toh ish mein kya karen plz reply 😢

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😂

Aditya Ranjan sir ; unique

This is eular number of 900 and this is known as eulaor theorm

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

3 saal pahle dusre teachers padha chuke hai ye😂

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

Etna esay solution, thank you sir ji ❤😊

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

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

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

Concept is outstanding

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

Sir, Jai Ho 🙏

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

This is called PnC prime no divisiblity rule

GOT of maths respect sir 🫡

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

वाह सर जी मौज कर दीए ❤❤❤

Permutation and combination ka concept use huaa hai

Permutations and combinations is very easy trick for any questions, Challenged he😊

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

Aaj jake ye bat samjh me aa gaya sir

Ye euler function ka question h "n ×euler function of[prime] divide by prime

Ye fotmula tabhi lage ga jab saare no yani ki 2,3 and 5 900 ko divide karte ho

Video cut karne se kuchh chhut gya Puri deep se define kre plz

Sir, we need to take numbers between 1 and 900 not from 1 to 900.....if take "between" there are 898 numbers in between them, how could it be 900?

Does not work for any number. Take 1 to 10 for example. With this, it comes 8/3 which is a fraction. The answer should be 2. Take 1 to 11. It comes 44/15. The answer should be 3.

Excellent Approach sir ji

Exactly best method 💯💯💯

Please give me answer this question sir. 1500 rupees two years me CI pe 3000 rupees ho jata hai to yah kitna time me 6000 rupees ho jayega

Sir Is Vedio par kam se kam 1 million+ views hote ❤❤❤❤ But hamari Generation Reels Dekhne me hi busy hai

Sir aap to dhoti khol rhe hai ❤❤❤❤ love you sir

to sir kab aarahi h video " last video of aditya ranjan sir"....???

Permutation ka box method😮 nice sir

Really useful ✨

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

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

Gajab khatarnak guru dev🎉🙏🙏🙏

Sir mai aapka bahut ijjat krta hu pata h ki aap achhe teacher ho But ye bolna bilkul anuchit h ki hm hi best

Bhut tagde guru ji
