This product will be even when one of factors is even.
If both factors are even, product will be divisible by 4.
As given product is not divisible by 4, it means one of factors should be even and other factor should be odd which is not possible with any set of integers.

Distance traveled with speed of 80 kmph= (1/4)80= 20 km.
Remaining distance=350-20=330 km.
Time taken to travel 330 km @60 kmph= 330/60 =33/6=5 1/2 hours.
Total time = 5hr [1/2+1/4], here (1/4=15/60)

Sixteen teams have been invited to participate in the ABC Gold Cup cricket tournament. The tournament is conducted in two stages. In the first stage, the teams are divided into two groups. Each group consists of eight teams, with each team playing every other team in its group exactly once. At the end of the first stage, the top four teams from each group advance to the second stage while the rest are eliminated. The second stage comprises of several rounds. A round involves one match for each team. The winner of a match in a round advances to the next round, while the loser is eliminated; the team that remains undefeated in the second stage is declared the winner and claims the Gold Cup. The tournament rules are such that each match results in a winner and a loser with no possibility of a tie. In the first stage a team earns one point for each win and no points for a loss. At the end of the first stage teams in each group are ranked on the basis of total points to determine the qualifiers advancing to the next stage. Ties are resolved by a series of complex tie-breaking rules so that exactly four teams from each group advance to the next stage.

total cost of three books=450+520+250=1220
now , initial discount=1220*10/100=122
so, total=1220-122=1098>1000
therefore,additional discount =1098*5/100=54.9
=>total saving=122+54.9=176.9
b. Rs. 176.9

The class Square is as follows:

using System.Collections.Generic;

internal class Square // version of 15-09-2015

{

private double m_Side;

private double m_PosX = 0;

private double m_PosY = 0;

public Square(double p_S)

{

m_Side = p_S;

}

public Square(Square p_Sq)

{

m_Side = p_Sq.p_Side;

}

public void SetPosition(double p_PX, double p_PY)

{

m_PosX = p_PX; m_PosY = p_PY;

}

public double GetSide()

{

return m_Side;

}

public static List PlaceInside(List p_Squares)

{

// YOUR CODE HERE

}

}

he method name and parameters are as follows:

public static List PlaceInside(List p_Squares)

The method PlaceInside gets a list of squares and returns them once inside each other with the same centre and placed so the biggest square lays on the X and Y axis (position of biggest = 0,0):

optimize the code by applying the following logic.
The LCM for 2,3,4,5 and 6 is 60.This means that 61,121,181 etc. gives remainder 1, when divided by 2,3,4,5 and 6.You have to check whether 61,121,181 etc are now multipled. Display and mention the number of iterations needed to generate in the first case and last case

A biased die has a probability of 1/4 of showing a 5, while the probability of any of 1, 2, 3, 4, or 6

turning up is the same . If three such dice are rolled, what is the probability of getting a sum of atleast

14 without getting a 6 on any die ?

in a throw of three dice total no of possible cases=6^3=216
now as 6 should not appear on any die and sum must be at least 14, therefore no of favourable cases=4
probability(getting 5)=1/4
suppose p(1 or 2 or 3 or 4 or 6)=x
since total probability of any sample space=1
so,p(1)+p(2)+p(3)+p(4)+p(5)+p(6)=1
x+x+x+x+1/4+x=1
=>5x=1-1/4
=>x=3/20
Now, p(getting sum 14 without 6 on any die)=(favourabale cases)/(total cases)
=4/216 = 1/54
Now, favourable cases are:
(5 4 5), (5 5 4), (5 5 5), (4 5 5)
therefore, required probability=1/54*{ ( p(5)*p(4)*p(5) )+( p(5)*p(5)*p(4) )+( p(5)*p(5)*p(5) )+( p(4)*p(5)*p(5) ) }
=>1/54*{ ( (1/4)*(3/20)*(1/4) ) + .....}
=>1/54*{ 3/320 + 3/320 + 1/64 + 3/320 }
=>1/54 * 14/320 = 7/8640 .
