@@mumutv7058 you are stand in class 10 okhh that's great but beta ji according to mathematicans he suggests a boy study in, 10th class so he should know that's this simple equations. This is not bigger then you'res class standard.
Let a=x^2,b=y^2,c=z^2,d=w^2. The biquadratic eqn is a/(t-1)+b/(t-9)+c/(t-25)+d/(t-49)=1 whose roots are 4,16,36 and 64. Now compare the coeff of t^3 ,we get a+b+c+d+1+9+25+49=4+16+36+64, So a+b+c+d=36(Ans).
It's a humble request from me please take a Special session on beautiful questions of calculus for jee Adv which help us to improve our thinking process for any question Please,Please,Please please sir🙏🙏🙏🙏🙏🙏 We want this session by you.this will be helpful for everyone. Please like to support this request.
Sir, solution dekhne se pehle maine try kiya, aur man me yahi same trick aaya ki sabhi equation ki denominator me jo numbers the unka kahi na kahi '2' number ke saath relation jarur hoga main aadhe tak pahunch gaya tha lekin equation solve nahi ho paaya😢😢.Thank you for the solution sir..
I finally did this question by myself sir 😭 i saw this question in june. and i tried it for long time and suddenly after 8 months i solved it. So much happiness really. I am a winner
Sir alag alag solve karte hein ek equation 4 variable. Pehli equation me koi teen variable 0 put karo, doosri equation me doosre teen variable 0 put karo,teesri equation me teesre teen variable put karo isi trah chothi equation me karo aur ek ek varibale value nikaalo aur unhe jod do answer 36 hi aayega
Amazing question sir!! Didnt expect ki equations merge bhi ho sakte hai... recently quadratic(2 degree) ke topic ke kuch sawal kiye the toh attempt krne ki koshish ki 😂 par question ki jagah mujhe ghutne tekne pade 😅. I was thinking to substitute values from 1st eq to 2nd and so on... par expand krne ke baad jo aaya use dekh ke samajh gya galat kr rha hoon!
I solved it by calculating which was very lengthy process and answer was approximately 34.___ and according to options it was 36 which was correct answer but calculation is little more

Nice informative video Sir. But something went human error in writing at 8:31 (To err is human.) This could have been x²(4k-9)(4k-25)(4k-49) Anyway nice explanation. Thanks.
Sir maine isse iss tarah sei kiya , PLEASE CHECK Maine yeh socha ki charo number ka square hai toh number positive ayega , maine x,y,z,w ko same number honge aise sochke chala kyun ki alag honge toh answer bada hota and option mein nhi hai utne bade answer . Kisi bhi 2 negative number ka sum positive ayega and 2 positive number ka sum positive ayega , hence isse yeh pata chalta hai ki answer odd nhi hoga toh 3rd option 25 eliminate hoga . Phir as maine assume Kiya tha ki sab number same honge toh mujhe yeh samjha ki sabka sum karenge and unhe 4 sei divide karenge toh ek non integer number ana chaiye ( kyun ki mostly long sums mein integer value normally nhi paayi jaati ) . Phir maine iss baat sei jana ki option 2nd 18 nhi ho sakta .phir maine 1st and 4th ko observe kiya and paya ki yeh x , y, z ,w inka value ek toh 2 ho sakti hai ya 3 ho sakti hai. Phir maine 2 put karke dekha 1st equation mein toh equal nhi aa rha tha . And 4th option bacha tha sirf , so maine usse select karliya . And jab check kiya toh sahi tha . So the answer is D option 36 3²+3²+3²+3²=36
Actually , this question is from aime (maths Olympiad) , came to in paper between 1985-1990 , I don't remember the exact year, i have done previously in maths Olympiad preparation, found it to be tough , because it reflects new idea change into (polynomial equation)but i remember this idea to apply on other questions .....
Sir I have a solution that if I Put the value of X by using denominators and other terms as 0,0,0 then from Ist eqn I get the value of X as√3 and waise baki eqn se bhi y,z,w mil jayega as √7,√11,√15 respectively . Humara and ho jayega tab 7+3+11+15 = 36 . Thanks sir for giving us good question
Kuch bhi nai karna hota question mai.. there is no. Point putting all zero but only variable value.. that is the wrong approach and there is no logic in that.
@Raj Chaudhary bhai theek sawal hai yeh, troll hai kyuki ajeeb sa pattern de rakha denominator me, aane ko ioqm 5 marker aa bhi sakta hai... IOQM jee adv jaisa hi hota hai (its not a proper olympiad, but rather a selection test for one)
Sir first of all thanks for the solution I took 1 hour to solve by assuming X2=a. y2=b and so on solved the linear equations and then get to the answer while solving I realised that there is something common in all the equations and by seeing the solution I got to know what is common..thanks Sir.

Im in 10th i guessed the question as everything is same only the first denominators are differing so i did 8-2 and as it is squared i did 6² and it is 36 i then try to understand sir method i tried and understood it...
Yaar pehla brute force approach to lg rha ki haan sare equations ko matrix form me arrange kr lo idhar. Phir dono side wo jo 4×4 wali matrix hai uske inverse se multiply kr do, bs x2, y2, sb mil jayenge add kr do.
Sir i made a grid of the values of denominator in question.....waha se around 10 mins tak usko ghoorta raha fir chamka ki 4k minus something ban raha hai.....uske baad ho gaya sawal
This question was so easy my cousin in class 2 did it in 2 min and i did it mentally in one min..... So easy, so easy, solving like a WOW...... Aise questions aayenge tho sabhi ka AIR 1 aa jayega.....

Sir, Mai jee aspirant nahi hu but Maine isko 4×4 matrix ki inverse nikal ke kiya, but iss mei inverse nikal ne ke baad bohot bade numbers agye the lekin mene bharosa rakha aur dekha ki w² ki value 25.707 something tha (x²,y²,z²,w² > 0) so isse Maine conclude Kiya ki answer 36 ayega
