2. A square was given and another square was formed by joining mid points of the square. If perimeter of larger square was given 'X'.
Col A: Perimeter of smaller square
Col B: X/2
3. Col A: (7!)^2
Col B: 13!
4. If f(n,k) = n!/(k!*(n-k)!), then
Col A: f(16,3)
Col B: f(16,14)
5. If product of xyz is odd integer, then which of the following is even
A. x(y+z)
B. xy+z
C. yz+x
& so on....
6. There is a series of odd numbers from 1 to n where n is a odd number. What is the probability that a number selected at random will be an odd number?

Allanswersare correct except forthe 1st and 6th one
1st Question
Col A: (2^8*(15^5)+(2^8*(15^5)
Col B: (5^10)*(8^2)
COLA:2(2^8 *15^5) = 2^9 * 15^5 = 8^6*5^5*3^5
COLB:5^10*8^2
DivideCOLAwith COLB =8^4*3^5/5^5 =(8/5)^4*(3^5/5) >1
ThereforeCOLAisgreater
6th Question
There is a series of odd numbers from 1 to n where n is a odd number. What is the probability that a number selected at random will be an odd number?
When the seriesis of oddnumbers,no matter what u take, it will be an odd number ,therefore the probability is 1
Please correct me if iam wrong anywhere -

Col A: Perimeter of smaller square
Col B: X/2
Can someone explain this problem for me
I am getting the perimeter of smaller square as x -

Hi Sivaraj,
for this problem, the diagonal of the samller squre is the side of the larger square,
let the side of the smaller sqre be b and that of the larger square be a,
then (sqrt2)*b=a
b=a/(sqrt2)
Now perimeter of the larger square =4a=X, X/2 = 2a
perimeter of the smaller square = 4b=4a/(sqrt2)=2(sqrt2)a
Therefore COLA is gretaer -

I think question 6 means 1,2,...n , both even and odd numbers. thus given answer is correct.

in 7th
consider the intercept form of equation
x/a+y/b=1, where a, b are x-intercept, y-intercepy respt.
so, xb+ya/ab=1
xb+ya=ab
ya=-xb+ab
y=x(-b/a)+b
slope -b/a=-1/2
thus a>b
so ans A -

so what about the line pass (0,0),then theX or Y-interpret are both 0
correct me thanks^^ -

Shoot On Sight is an entertaining drama that addresses racism, politics, .. and terrorism.. It isn�t preachy � just fascinating.. But in the end it pays off as a good, old fashioned police thriller
