There is a group of 200 students, where each student studies one or more of the three subjects among Aeronautics, Biotechnology and Cryogenics. The number of students studying cryogenics is more than the number of students studying aeronautics, which, in turn, is more than the number of students studying Biotech, which, in turn is more than the number of students who study exactly two of the three subjects, which in turn, is more than the number of students who study all the three subjects. It is known at least 1 student studies all the three subjects.
1. What is the maximum number of students who study Biotech? (148,148,150,147,None)
2. What is the minimum number of students who study Biotech? (67,68,69,70,None)
3. If exactly half the students study cryogenics, what is the maximum number of students who study all three? (30,31,32,33,None)
4.What is the maximum number of students who study only Aeronautics? (100,99,98,97,None)
APPROACH is what I am looking for ...
For these type of questions by drawing Venn diagrams
let studying only Aeronautics ,Biotech and Cryogenic be a,b,c
studying both A and B but not c=d
studying both B and C but not a=e
studying both A and C but not b=f
studying all 3 be x
For 1st: I concentrate on maximising x here in this problem.So I put a=b=c=0.And then put d=0,e=x/2,f=x/2+1 to satisfy the given condition of C>A>B>Exactly two>All three. Then it becomes 2x+1=200. The maximum value of x here can be 99.Hence,x=99,e=50,f=51.Hence B=99+50=149. Sahi hain kya bolo???

mujhe isme koi flaw nai dikh raha..all conditions are met.
A. 창€œThis face-off will continue for several months given the strong convictions on either side,창€? says a senior functionary of the high-powered task force on drought.
B. During the past week-and-half, the Central Government has sought to deny some of the earlier apprehensions over the impact of drought.
C. The recent revival of the rains had led to the emergence of a line of divide between the two.
D. The state governments, on the other hand, allege that the Centre is downplaying the crisis only to evade its full responsibility of financial assistance that is required to alleviate the damage.
E. Shrill alarm about the economic impact of an inadequate monsoon had been sounded by the
Centre as well as most of the states, in late July and early August.

I don't mind watching dead rubbers till the time the quality of football is good. I am a big barca fan, however I still believe if theres one team that can beat barca with their own pass-move-pass game, that has to be arsenal. And Barca-Chelsea and Barca-Real is more a test of courage, endurance and big match patience and less of real quality football.. Having said that, I respect all teams for their quality. I ain't no Zidane to comment on them. It is just my opinion, and all respect to your opinion as well
True man....But for a neutral a dead rubber is awfully boring and what u have said is all true which is why Barca-Real is such an anticipated match.Its like saying XAT is better than CAT in terms of quality which might be true but the sheer pressure and the reward involved in CAT makes it more worthwhile and prestigious than XAT and its the same with these matches.
