One number added, average increases by 1.
Og avg = 55
New avg = 56
New number brings in 13 more which can be distributed between the 13 new numbers to increase avg by 1.
Originally there were 12 no's. Let the first 11 numbers be the 11 smallest distinct natural no's. S11 = 66

Q. M is a set of distinct positive integers whose average is 55. If a number 68 is added to this set, the average increases by 1. What is the largest number that can occur in this set?

Filhaal main ek sectional analyze kar raha hu, jo sahi lagte hai daalunga.
I was going to go through the thread after I am done analyzing.

Thode aur ques daal na...I had emptied my basket yesterday.Did you go through them?Some of them are nice,conceptual ques. Will have to research for more ques.
Ab hum jaise log mock ka load lene lag gaye hai na, toh dikhna band ho gaya hai saala.

Didn't strike that C has to be negative since (A>0) I.e product of roots <0 Nice work,man. :)
Thoda sochna pada...Novel question tha mere liye.Hadn't seen anything like this before. I was thinking f(0)<0 as imaginary roots. :P See, (x-alpha)(x-beta)<0 for f(0)<0 either x-alpha>0 and x-beta<0 alpha can be 1,2 and beta can be -1,-2,-3 =6 solutions. or x-alpha...

Haan yaar, bahot easy tha. Har test ke first question ka usually main yehi karta hu. :P
too much of speed reading? I was also wondering ki easy to tha...
Arey yaar, tera solution padhne ke baad realize kiye ke condition f(0)<0 hai, main kabse f(alpha or beta) < 0 soch raha tha..
oye 18 ans hai kya?
basically C negative hona chahiye
product of roots =C/Aif a is +ve then c has to be -ve and that will happen if either alpha or Beta are -ve.
alpha has 4 -ve valuesbeta has 3 postive values12 iske bante hai
similarly alpha has 2 positive and beta has 3 negative v...

Q. Given that f(x) = Ax2 + Bx + C (A > 0). If f(x) = 0 has integral roots α and β such that –4 ≤ α ≤ 2 and –3 ≤ β ≤ 3, then for how many distinct pairs (α, β), f(0)< 0 ?

Guys,let's know each other meanwhile.
Kya kya shauk hai yahan loge ke apart from doing alpha,beta and what are you good at(No worthwhile activity should be mentioned!)

The point should always lie on the line dividing PA and PB in ratio 2:1
So,I guess it has to be the straight line passing through origin dividing the triangle in ratio 2:1
BCZ
height x base1=2(height x base2)
height is same.
So,ratio is ultimately-
Base1=2 times Base2

@Zzeke said:
Let O be the origin and A, B be two points having coordinates (0, 1) and (6, 0) respectively. If a point P moves in such a way that the area of ∆OPA is always twice the area of ∆POB, then P lies on ay2 = 9x2 bx2 = -9y2 cx2 - 9y2 = 0 dy2 = – 9x2 eNone of these
None????
If A-P-B, then P (4,1/3) which satisfies none of the options.

Didn't check the original eq.When you keep y=6 then log2 (5-y) will be invalid.

Saale, text chat. Ab tu paka raha hai. Chup chaap se aa ja. :P
Aur meri fatt chuki hai ab... Quant jald hi sambhle toh achcha hai. Sirf accuracy ka load, baaki attempts, concepts, etc. most bases are covered. :(
Haan, mocks main decent ban rahe hai na toh UDT khud hi ban gayi.. :)

Important cheez ye hai ke, log main variable daalo toh ek aur condition check karni bach jaati hai..

acha we gt root(xy) as 6 so xy = 36 so 9&4 combination possible but dis does nt satisfy 1st eqn ,....but 8&4 does...so xy=32...

Aur accuracy?

Mera ab ulta ho raha hai, Quant is awesome, VA is mindfucking my case :/
25 attempts 10 wrong :/ (CAT 2008)
Will try. Invite kare rakho. Kahaan pe hai woh bhi bata diyo. I can come to andheri :)

Wow! The solution was just damn brilliant.
Learnt something.
Nope. Koi bhi mock deneka mood nahi. Saala quant ne pooch pakadke rakhi hai. :(
Raat 10 baje confy hai, aayega na?
