Please verify, I am also be wrong.
4) The answer is D, not A but i am not 100% sure
6) It is given the two points are equidistant from point(x,y), so use mid-point formula
{(3+3)/2, (0+3)/2} => (3, 1.5) -

2) B
Cool A (61)
14) B
for the 6th one i thnk its B charanj wat u've done found the mid point between two points
but according to the coordinate system both hav same x coord
they differ only at Y -

Hi,
14) It is D. Check for values (1,2,3) & (2,10,1Cool
Cool How did u get 61?? (180-(58*2))
6) I think it is D, considering your explanation point (x,y) can be on the line joining (3,0) (3,3) or it can be to the left or right. So value of x varies accordingly.
2) Can u pls explain how u arrived at the solution?
Thnx! -

14) charan for the values which u hav said
0<1<2<3
col A) 1/2=0.5
col B) 2/3=0.6
col B is greater
0<2<10<18
col A)2/10=0.2
col B)10/18=0.5
stil it col B which is greater
6) i'm also not sure abt 6th one i think any point from wer they must be equidistant should definetly be below their X coord 3 so i thought it was B
but i'm not sure. -

2. If n > 10,000, then which of the following is the closest to 3?
A. 1/(3^n)
B. 3 + 1/3^n
C. n/(3^n)
& so on....
ans- for n>10000 A. it is definetly 0.0000 some value
B. it is 3 + 0.0000 some value
C. its denominater is greater than numerator so this also must be 0.0000
so there's only one possble solutn ie B. -

for the 6th one the answer has to be D) bcz the value of x can be either 2 or 3 or 4 n all the the points would still b equidistant from (3,3) and (3,0).

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
