Answered: Zeal Test Series 2019: Graph theory - Vertex Cover

let matching number=M , independence number=N , edge cover number=E, vertex cover number =V given that V-E=2k , M*I=1-2k ----(1) and we know that V+I=n and M+E=n (n=number of vertices) V-E=M-I=2k ---(2) we need M+I so we know that-- (a+b)^2=(a-b)^2+4ab (M+I)^2=(M-I)^2+4MI from eq(1)and (2) (M+I)^2 = 4k^2+4(1-2k) =4(k^2-2k+1) =4(k-1)^2 so M+I= 2(k-1) [...]

Answered: Sheldon Ross, Chapter #4, Question #13

P(Passenger $x$ shows up) = 0.99 for some passenger $x$ P(All passengers show up) = $(0.99)^{51}$ = 0.599 Revenue from 51 tickets = 51 * 10000, irrespective of how many passengers show up Loss if all passengers show up = 100000 Loss occurs with probability 0.599 Therefore, net income = 51 * 10000 – 0.599*100000 = 4.5 Lakh [...]

Answered: proposition logic

lets say P(x): x is a person L(x,y): x loves y so the above statement is ~(everyone who loves someone is loved by someone) ~∀x[ (P(x)∧∃y p(y)→L(x,y)) → ∀z(P(z)∧L(z,x)) ] [...]

We use hierarchical access Using I cache: Tavg1= H1T1 + (1-H1)(H2)(T1 + T2) + (1-H1)(1-H2)(T1+T2+T3) = (0.8*0.2) + (0.2)(0.9)(10) + (0.2)(0.1)(100) = 5.4 ns Using D cache, Tavg2 = H1T1 + (1-H1)(H2)(T1 + T2) + (1-H1)(1-H2)(T1+T2+T3) = (0.9*0.2) + (0.1)(0.9)(10) + (0.1)(0.1)(100) = 3.7 ns Now Tavg = (60% of Tavg1) + (40% of Tavg2) = 4.72 ns [...]

${\color{Blue} 5} $ ${\color{Blue} most} $ ${\color{Blue}expensive } $ ${\color{Blue}books } $ Just make a random table, and then, use two pointers T and B, now, just iterate the T pointer for each of B pointer You will realise, this is like a nested for loop implementation. This property is the soul of nested sub queries You have to take example and solve Now How easy it becomes Thanks Shashank [...]

Answered: NIELIT 2017 DEC Scientific Assistant A - Section A: 6

All of the girls agree that the first three numbers are 995. Three of them agree that the fourth number is 9. Three agree that the fifth number is 2. Three agree that the sixth number is 6; three others agree that the seventh number is also 6. "Option A" is the best choice because it is made up of the numbers that most of the girls agree they saw. [...]

Correct Answer: (D) Explanation: This game introduces the idea of reciprocal causation. For example, the constraint that says “If A, then B, and if B, then A” should be transcribed in one of the following two ways, based on the configurations of the other variables in the diagram: You will run into reciprocal causation in the final constraint of this logic game. Here are the final diagrams that you should create: Notice how the reciprocal causation constraints are diagrammed. Be aware of the implications of these constraints. For instance, if $B$ is not sent (diagram B), then $A$ cannot… [...]
