What is the right time to start giving mocks??
In a study of traffic flow in a section of the CBD two intersections are selected to be analysed. The intersections are chosen to have integer coordinates (X1,Y1) and (X2,Y2) where 1<=X2<=X1<=4, 1<=Y1<=3, 1<=Y2<= 3 and Y2 >= Y1.
The intersection at (X1,Y1) is chosen first, with probability distribution given by Pr((X1,Y1) = (x,y))= c /x , for some constant c ∈ R.
The intersection at (X2,Y2) is chosen second and is selected uniformly at random from the choices that are compatible with the location of the first intersection. Let A be the event that X1 > 3, let B be the event that Y1 > 2, let C be the event that X2 = 3 and let D be the event that X1 = 3.
(a) What is the value of c?
(b) What are Pr(A) and Pr(B)?
(c) What is Pr(A∩B)?
(d) Use your answers to (b) and (c) to find Pr(A∪B).
(e) Are the events A and B independent?
(f) What is Pr(C | A∩B)?
(g) Use Bayes’ Theorem to find Pr(D | C).
(h) Are the events D and C independent?
A student took five papers in an examination, where the full marks were the same for each paper. His marks in these papers were in the proportion of 6 : 7 : 8 : 9 : 10. In all papers together, the candidate obtained 60% of the total marks. Then the number of papers in which he got more than 50% marks is? [Pls solve this ques.]

I have heard numerous times "Give mocks.. Analyze them properly"..
Here is my doubt: "How to analyze mocks? What should be running in mind while analyzing them? "
If anybody can give indepth procedure of mock-taking plus analysis part (if possible, categorised section-wise), would be really helpful.. TIA
At 7:00 A.m. Anil started from P towards Q and Bhanu started from Q towards P at 9:00 am. They crossed each other and moved towards their respective destination. If total time taken by Anil is three hours more than time taken by Bhanu, find ratio of their speed.. O.A. - 1:2 APPROACH???
