sry the answer to 7th is 11\14.

let smaller candle's length be s
it burns out in 11 hours i.e. s\11 per hour, so in 3 hours length = s - 3s\11 = 8s\11

similarly for larger, 4l\7

therefore, 8s\11 = 4l\7 , s\l = 11\14

but their width r not same. if width r same then its fine. please explain question no 1 and 2

wt bt thickness???
length waala portion is fine....yehi mera doubt hai hw to handle tht thickness....
i thot of 11= L1 * T1
so for 3 hrs...it will be 3L1*T1/11
so the left amount be 8L1*T1/11
similarly we can get it for the second candle
left amount will be 4L2*T2/7

equating both we get

the equation in L1,T1,L2,T2 unless we assume T1=T2 we cannot get the ratio of L1 and L2

chalo lets c wt others hvto say

lemmings is right. Thicknes affects only speed of burning(i.e. length unit/hour), which has already been taken into account, so not again

sry the answer to 7th is 11\14.

u hv th method fr 7??

3. Good ol' calculations :D, try doing the calculations on last step, more often than not lots of things cancel out.

7. Convince your brain that simplest solution is usually the right one.

I know ppl who got screwed must be feeling highly dejected.....just one wrong bubbling did the whole thing....
nxt time onwards make sure wt u are filling check atleast two time wht u have entered coz these sarkari ppl dnt think before cancelling the answer sheets...machine me daala read nahi kiya toh cancel....so plz plz follow the instructions and even if invigilators are there to assist u dont depend on them as they are just there to make sure the test is smoothly run and it is expected that they dont know anything bt the details or the info that u need to furnish on the answer sheet...everything needs to be furnished properly and it is clearly mentioned on the instruction booklet or on back of the admit card....

having said that still there are instances when ppl are fooled by some unavoidable circumstances or extreme back luck....toh yaar we dnt have control over that....out of 40k who have been rejected it was expected that roughly around 1-2k make it to the next round....so really really a misfortunate...SSC should learn frm such instances and why the hell u have to usse such codes where there might be ambiguity between O and 0...
itne numbers and alphabets hai duniya me unhe aisi hi ek number mila kya....simple coding honi chahiye....AB 01, AB 02, or CD 01, CD 02...
why the hell they want such codes....

yar dekho galti kisi se bhi ho sakti hai,,last time i prepared hard even more than this time,,i attempted 170 around qs correct,bt when i heared 5 min bell,i quickly started to dark bubbles, i missed half of maths & all english question to attempt, i got 89 marks,,with 21 in maths & 0 in english,,got disappointed as invigilators didnt gve me even 5 min more, this time i didnt prepare for this , may be i got 105 marks,i m cleared for tier 2 , but with less score,

aur islie khud ko bhi dhyan rakhna chahie ki kya roll no likh rhe ho,,sbse bdi bat ye hai,ki mana call letter pe galat no likha hai,pr sbke sb jo aapki class me the wo is wajah se fail nhi hue,i m surprised how you reached at right seat right room after seeing sitting arrangement which was adhered at exam center,shows correct roll no's,,do not blame others,,even when you r not careful

Active-The police arrested the thief. Passive-the thief was arrested. But here the subject is not vague. Please explain.

In passive voice sentences you are at liberty whether or not to mention the doer of the action if the doer can be easily identified.That is, "The thief was arrested by the police" mentions the doer of the action(Police).
In case of "The thief was arrested" , the doer of the action can only be the police as they only have the authority to arrest anyone. The second question carries the same explanation
Another example:The window was broken(by somebody)

1. Lets divide the pages from 1-99,100-199,200-299,300-366
all digits occur 20 times from 1-99
so 20(1+2+3+..9)=20*45=900
for 100-199
1 occurs 100 times more hence 900+100=1000
for 200-299
2 occurs 100 times more hence 900+2*100=1100
for 300-366
3 occurs 67 times more hence 900+3*67=1101
so the sum of all the digits is 900+1000+1100+1101=4101
number of digits from 1 to 9 is 9
10 to 99 has 90*2=180 digits
100 to 366 has 267*3=801 digits
total=9+180+801=990
sum of the digits is 4101 and there are 990 digits

2.
starting from 1-9 he uses 9 digits
from 10 to 99 he uses 90*2=180 digits
from 100 to 999 he uses 900*3=2700 digits
adding these we get 2889 digits
lets subtract this from 3189 , we get 300
300/4 will give number of 4 digit pages numbered which is 75;
hence the number of pages is 1000+75-1 (subtract 1 to exclude 1000 which been included in the 75 pages ) ie 1074

A maid gets 120+blouse for 8 mnth as salary.she works for 3 mnth and got a blouse only.find d cost of blouse?

lets rely on good old empirical approach here
Let salary per month be x rupees and cost of blouse be y rupees
so her salary after 8 months is 8x
clearly, 8x=120+y
and 3x=y
substitute second equation in the first one
8x=120+3x
5x=120
x=120/5=24
y=24*3=72 which is the answer

lot of thanks. u cleared my problem. thanks again.

We can use Arithmetic Series Formula here.
First Term:1
Last Term:100
N:100

Sum of Terms : n (first term+last Term) /2
= 100(1+101)/2
Answer: 5050

The question is about the sum of the digits and not the actual sum.

I dont what method you have adopted but sum of series 1 to 100 can not be 901 in any case.
Just simply add 90,91,92.....100 It crosses 901. Simply 90*100 =900.

Check your method again bhai....

Hey, mate the question is the sum of the digits of the numbers from 1 to 100

all digits from 2 to 9 occur 20 times
whereas 1 occurs 21 times because of 100

so the sum of the digits is 20*(1+2+3+....9)+1=20*45 +1=901
The problem in the picture can be solved easily by remainder theorem;substitute x=1 and the remainder is 0

puys that list of candidates who got zero marks in tier 1 doesn't shows the roll no. then how come you guys came to know that you are given zero marks

1. Staff Selection Commission Combined Graduate Level Examination, 2011 (Tier I ) Details of the candidates awarded ZERO '0' marks The Staff Selection Commission conducted the Combined Graduate Level (Tier-I) Examination, 2011 on 19.6.2011 and 26.6.2011 all over the country. The result of Tier-I examination was declared on 22.7.2011 wherein it was inter alia stated that the marks of non-qualified candidates and cut off will be made available on the Commissions' website after the result of the candidates appearing in Re-examination scheduled to be held on 31.7.2011 is declared.
2. The list of 38216 candidates who have been awarded ZERO marks due to wrong coding of their particulars (Name, Roll Number, Ticket Number, Test Form No. and without Signature etc.,) on the front page of their OMR answer sheet is now placed on the website. There are around 900 candidates who have wrongly coded or not coded their Name, Roll Number, Ticket Number, Test Form No. and without Signature etc., on their OMR sheets and, therefore, no other details except ZERO has been indicated in the list. The abbreviation used for the purpose of indicating rejection are as under: TF No. - Test Form Number T No. - Ticket Number WS - Without signature Name - Name Roll No. - Roll No. 3. The list is also available on SSC's website Welcome to SSC. (Satya Prakash) Under secretary C.I(1) 29.7.2011



NOw it clearly says that candidates have wrongly entered wrong TEST FORM No. BUT NOT THE SSC.
So once again SSC is safe and candidates will suffer.They wont entertain any RTI if ur roll call is in rejected list.

IDIOMS:
ant in one's pants: a state of restless impatience
cat nap: a short sleep
cat got one's tongue: expression used when somebody is quiet, to someone else's surprise
chicken out: back off, remove oneself from an obligation

Ibnlokamat

My Rejection Reason is TF -Test Form Number.
But in my case it was not my fault. it was SSC`s fault
In my form number at second place 0(Zero) was written but in corresponding OMR bubble instead of 0(Zero) Alphabet o was there
So i darkened o instead of Zero( Because 0 was not in OMR Sheet.)

So this was not my mistake..........SSC is responsible for that

Now what i can do...?
