can u xplain Q 4 n 6 ...

Anonymous said...

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

Anonymous said...

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.

pls give solutions for 17 th and 18 th que ,,,,

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).
