can some1 explain ques 23 and 11..in 11 i didnt get that y did we take a buffer slot..and plz throw sm lite on 23 too

- see, in question 10 N (5,5)- N(5,4) meant the number of n.... 4m.

see, in question 10 N (5,5)- N(5,4) meant the number of numbers with at most 5 digits and sum of digits EXACTLY 5. So, in ques 11, to determine the value of N(6,5) which is number of numbers with at most 6 digits and sum of digits at most 5, we need to calculate the number of numbers with at most 7 digits and sum of digits EXACTLY 5 and subtract 1 from it to get N(6,5). As explained in the solution, the sum of the digits from box 1 to 6 varies from 0 to 5, but for 7 boxes it is exactly 5. so, when we subtract 1, we get the desired result. Hope I was lucid.

P.S.: I got this question wrong

Something off topic :
But has anyone been solving the sectional tests of CL ?? I found it _utterly tough_ (Sorry for the vernacular language :P).But seriously , LR's were not arduous , but were something different.And to add more to this , it was of 40mins only. @MJ477 , @jay3421 , @Sabya1590

I learnt it somewhere , wanted to share it :

example 1 => trick for a<= b<= c<= d<= ....<=n

number of ways in which 5 numbers or n numbers can be selected from 1 to 9 , such that a<= b <= c <= d <= e

is 13C5

solution :

a will always be less than b+1

b will always be less than C+1

c < d+1 and so on

in short ,

a < b+1 < c+2

as max value is 9 , so , e+4 can be 9+4 = 13 maximum

in short , select any 5 numbers from 1 to 13 viz 13C5

Read the argument below & answer the question that follows:

The G20 should identify those
countries most at risk from global recession and ensure they are part of
the solution. It should ensure that the voices of the poorest and the
least powerful are heard and respected. Global recession should not be a
pretext for global repression. The economic crisis will bring added
pressure on governments from millions of newly unemployed people. There
is already much talk of a difficult year for China, for example, as it
faces a growing number of popular protests as economic growth slows.

The author’s argument assumes which one of the following?

20CommentsYes sure and you too keep sharing valuable tips so 97 was 1515N's score?

My whole strategy is going wrong. In the 60 question format i used to scan through the whole section at once and then I used to attempt the easier questions first. Scanning 50 questions on each section at first is taking up quite a lot of time. Also sometimes I end up wasting time on difficult sets.

Any suggestions guys?
