Two logicians place cards on their foreheads so that
what is written on the card is visible only to the other logician.
Consecutive positive integers have been written on
the cards. The following conversation ensues:
A : I dont know my number.
B : I dont know my number.
A : I do...
Jojo Gogo Pogo
------------------------
Caes 1: 2 4P P
Case 2: J 6J 2J
Case 3: ? 2x x
2J - P = J - 2 ---- (i)
6J - 4P = J - 2 ----(ii)
x - P = 2x - 4P --- (ii)
Solving above we get

A foreigner studying the weather of mumbai City for N number of days observed that:
1.It rained on 7 days, morning or evening.*
2.When it rained in the afternoon it was clear in the morning.
3.There were 5 clear afternoons*
4.There were 6 clear mornings.
What is the value of N?
When Jojo was two years old, Gogo was four times as old as Pogo. When Pogo was twice as old as Jojo, Gogo was three times as old as Pogo. How old was Jojo when Gogo was twice as old as Pogo?
a. 9
b. 6
c. 15
d. Data insufficient
e. 18
1. option A.4
2. option A.2
3. option D. CBD (5,6)
lol.. yeah.. :cheerio:
I think the concept of saddle point is pretty much clear to all of us now. But now, look at the question that started all this hulla ballo. There is no where given in the questions that students were standing as per there height? So.. I think that change our answers.
does the share prices increase and decrease in multiple of 10 or only by 10. can it remain constant.
D>A>B>C

Two traders, Chetan and Michael, were involved in the buying and selling of MCS shares over five trading days. At the beginning of the first day, the MCS share was priced at Rs 100, while at the end of the fifth day it was priced at Rs 110. At the end of each day, the MCS share price either went ...
i am sorry for spamming but there is no activity here for so long. What is everybody doing these days. Am i missing something !!!
i remember doing a c++ program in my class 12th(in 2003 n nevr touchd programming after that) where we used to check whether a matrix contains a saddle point or not. so, there may or may not be a saddle point in a matrix. yeah, it is there once the matrix has its elements arranged in some order ...

Hehehe... thats whr we both got stuck. So i think that it should follow some ascending/descending order.
k.. I read the qstn carefully.. (I got that qstn wrng earlier)
Your example is fine as per the concept. But If we consider the matrix given by jaidev_iyer(quoted above), the answers for columns and rows come out to be 4 n 5.
and I think the concept goes fine if we impose a condition with t...
Yeah..thats what I meant when I said I was getting arbitrary and inconsistent results in my earlier post.
Anyways, thanx a lot for ur participation. Let us know if you find anything which throws some (more) light onto this.
It was interesting to search about saddle point concept.. But its a purely mathematical topic with too many axioms nd theorems.. Its hard to reach conclusion but i think that the data should be arranged in regular order. I too lack much information abt this topic.
A and B r coming same in that matrix... i checked it once again..
in the worst case scenario........out of 70 muslims all 40 gujratis are muslims....so 30 muslims are bengalis.........for any variation in the gujrati side...no. of bengali muslims will increase....
so A. 30 or more seems correct

dude I dont think we can get answer as option 4,niether I think that we can apply saddle point concept here..
take a 3X3 matrix ( the one u have shown) I think A n B coming different.
Maximum number of gujarati Muslims possible is 40. So, we are left with atleast 30 muslims who have to be bengali.
So, Option A.30 or more
I hope I am posting this prob in correct Thread:
In a group of 120, 80 are bengalis ,40 gujratis, further info,70 persons are muslims and remaining hindus.
No of bengali muslims are:
1.30 or more.
2.20
3.between 15 and 25
4.between 20 and 25

here saddle point is 3, isnt it as per our question?
Thank you.
But when I tried doing the problem by reducing the problem to a 3*3 situation, I was getting arbitrary and inconsistent results.
Hope this definition will make r point clear -
When looking at a horse saddle, the saddle point (i.e. the centre) is the lowest point on the structure in the longitudinal plane whilst also being the highest point on the structure in the lateral plane. Therefore it can be considered geometrical...
