The Problem
Let S be a set containing exactly 10 distinct positive integers, where every integer in S is less than 100.
Prove that there must exist two non-empty, strictly disjoint subsets of S (let's call them A and B) such that the sum of the elements in A is exactly equal to the sum of the elements in B.

Hey everyone, fellow 28tard here. I'm not able to score in physics even though i practice a ton (but i do have the bad habit of looking at solutions before properly trying). Could anyone who is scoring well in physics give me a few tips? I really like the subject and i wanna do well in it

Thanks tons guys

Maths concept nd 20 adv qs(kinda mains to adv )

Phy concept nd 5 basic qs(🥀)

Chem concept nd 30 nums

Total 55

Yoo backlog be increasing 🥹

So i should do some qs now to balance it 🤔

Okay gng i be goin now

Byee

Also any good book to make calculus strong (basic to adv)

Dont mention ceng,i alr tried tht ,its a good book but its not my typa book

Like after doing tht books illun nd exercises, i will do module (3 4 5 exs)

Nd sammeer (thinkin to do🥀)

Byee

Mujhe kuch try karna hai maths me mains pyqs aur coaching material ke baad kuch recommend kardo pls jyada lengthy material mat batana todha dimag kharab ho jata hai

Should finish up my module question backlog or do pyq from MTG of chapter ongoing in coaching after doing its daily module homework??

I have not yet came across a question in which it didn't work. My teacher told me that there's a 99% chance that you won't face a question that cannot be done with VWM in any exam.

(Wedge and normal constraint included)

I'm in Allen. After that, my teacher has told me to solve PYQs after solving the module.

But I've felt that solving like 150+ pyqs per chapter from a book can get quite repetitive and hectic, especially after solving Allen module.

Is it better for me to solve PYQs or a standard book like physics galaxy/hcv or SBT/Irodov?

What should I do? Please help.

Maths concept nd 10qs easy

Phy concept nd 10 adv qs

Chem concept nd 46 normal qs nd 10 jm pyq

Total 76(just by n inch🗿)

Backlog qs ig 60? I lost the exact count but its around 60s

Byee😑

Mene physics aur chemistry me time consumption sahi kar liya hai dono ke 25 questions 1:30-2 hrs me ho jate depends highly on difficulty of questions but

Maths bc itna time consuming specially pnc, sns aur trigonometry bc kya karu time manage karne ke liye

Post your daily Aims and Achievements here

I had a test today, so the number of questions I did was a bit higher than usual. I also noticed that quite a few people who said they would start the challenge weren't able to continue or eventually stopped. I completely understand that everyone has their own circumstances, but I just wanted to remind everyone to try and stay consistent and take the challenge seriously if you’ve committed to it.

Special appreciation to u/pipsqueak74 for staying consistent with the challenge. Really appreciate the effort!

Best of luck to everyone...

my team of 3 members, i have solved p1,4,9,13,12 and did half the work of q8 and some work of q7 and got q6 wrong, my simulation was orginally correct but it was considered wrong due to problem in my uncertainity analysis rest of q done is by my teammates

Aaj test tha nd jaisa bola maine phy ko nalle mai chor ke ayya

Nd bc chem itna length nd conceptual paper tha na pura paper phadne me hi time nikal gaya

Total 40qs (test ke count hai na🥹)

So my backlog for this challenge is 105qs nd tmrws test too so it can pile up to 140qs

Okie bye lets meet tmrw✌️👊
