Hw Let no.of books be x Cost of 1 book =80/x Cost of 4 books =80/x+4 80/x-80/x+4=1 80x+320-80x=x^2+4x 320=x^2+4x X^2+4x-320=0 (X-16) (x+20)=0 X=16,-20 No. Of books can't be negative Hence no. Of books are 16 Hope this is helpful 😊😊
X= +16 . Therefore 16 No.of books he buys each at rate 5rs each. And if he buys 4 more books then (x+4)= 16+4 = 20 books 80/20= 4rs. He brought 20 books each at Rs 4 each Sir plz do videos about these tricky problem sums ....thank you sir
(number of books)*(original cost of one book) =80 (no. of books +4)(new cost of one book)=80 original cost of one book = 80/x (x is number of books) new cost of one book = 80/(x+4) given, original cost - new cost = 1 => (80/x) - (80/(x+4)) =1 by solving the eqn, x=> -20,16(-20 is not valid) 16 is the answer
Sir as u said in that tap question it is very much required to have a full session only on these sort of questions , sir please conduct a session like that if possible .
sir pls show how download the test series pls sir ,this issue is not just for me it is for many others,sandra mam said today she will send how to download or show ,, pls sir i want to utilise the resource u sent pls sir🙏🙏🙏🙏🙏🙏🙏🙏
45:54 sir athula namba normalaa veu eduth namaku root 2 varuthu sir [single answer] but id they mentioned to do like do in nature of equation like that then only we need to do like that aaa sir plz tell me

16 is the answer sir
🎉
1:22:19 word problem separate class venum sir😊😊
Class 10 2023-24 batch attendance here👇👇
Hw
Let no.of books be x
Cost of 1 book =80/x
Cost of 4 books =80/x+4
80/x-80/x+4=1
80x+320-80x=x^2+4x
320=x^2+4x
X^2+4x-320=0
(X-16) (x+20)=0
X=16,-20
No. Of books can't be negative
Hence no. Of books are 16
Hope this is helpful 😊😊
thx bro
😂
Lol
1:05:13 - 1:24:31 important question
Thank me later
Thanks ❤
Thanks🙂
thanks
Need more sections like this sir.....❤
sir separate video for word problem, please sir.
1:14:50 😂😂😂😂😂😂😎😎🤣
Sir, pls teach circles and statistics before solving PYQ's sir🙏🙏🙏🙏🙏. Please sir. If you are okay with this pls like this comment sir🙏🙏🙏🙏🙏
hats off sir because of i am understanding mathematics clearly thank you so much sir
very useful sir adad🔥🔥🔥🔥🔥🔥
Legends On The Day Of Board Exam 🔥🤙🤟 Today Board Exam 🤧
😅yes
Me tooo😂
Me too😢😅
Thank you sir
🔥🔥🔥🔥🔥🔥🔥🔥
yes sir
1:22:19 separate class please sir 🥺🙏
Iam seeing the lecture after one day sir but it is very useful 😊😊😊😊😊
16 books and price of each book is 5 rupee's
What books which subject
@@Journey_of_voicebruh did u watch the vid lol
@@AbdulHameed-o9q8c ig that person didn't watch 😂
Sir do for arithmetic progression also
Thankyou for your hard work sir 😊. ❤
1000th like sir
Any 2025 batch assemble here 👇👇
Sir for word problems thaniya video podunga
X= +16 . Therefore 16 No.of books he buys each at rate 5rs each.
And if he buys 4 more books then (x+4)= 16+4 = 20 books
80/20= 4rs. He brought 20 books each at Rs 4 each
Sir plz do videos about these tricky problem sums ....thank you sir
Super session sir 🔥🔥 very much useful sir. Adad 🔥🔥🔥
❤🎉😢
sir we need word problem questions for applications of trigonometry sirr
(number of books)*(original cost of one book) =80
(no. of books +4)(new cost of one book)=80
original cost of one book = 80/x
(x is number of books)
new cost of one book = 80/(x+4)
given, original cost - new cost = 1
=> (80/x) - (80/(x+4)) =1
by solving the eqn, x=> -20,16(-20 is not valid)
16 is the answer
super useful sir🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
Thank you sirrrr😭😩hats off💗😭🦋
Sir we need seperate session fr word problem
Sir word problems vennum
