if    A=ankur does right      and          R=ramesh does right
P(A)=1/8          P(R)=1/12
 
now both do same mistake P(A^R)' =1/1001 so P(A^R)=1-1/1001 = 1000/1001
 
so the probebility of  correct answer is P(A' ^ R' )'     [in ankur & ramesh  any
                                                                              one gets correct answer
=P(A)+P(B)-P(A^B)
=1/8+1/12-1000/1001
= -18995/24024                                                                                         we will get it.we have
 
                                                                             to find P(A' ^ R' )' ]

if you write i,j & k in traingle shape like         i
                                                              k     j
and moves to clockwise direction you will get
 
i * j = k , j * k = i,k * i =j
 
now if you moves anticlokwise direction
 
i * k = -j , k * j = -i , j * i = -k

in sp3 hybridization one s and three p orbitals hybrides.if we take methyn there is sp3 hybri.in it in carban it has one unpair elecrone in s orbital which attached with three elecrones of p orbital and makes four same staringh sp3 bonds.

are you sure with the ans? i don't think so it is right.
 
if deector is moving in +ve x-axis direction &soruce in -ve x-axis direction
then
                                                                  for both V&Vd    =a*t=20
       fs/V-Vs =(f)d /V+Vd
so fd=fs(330+Vd) / 330-Vs
 
     fd=330+20 / 330-20
fd=35/31 khz

is it stright line between b &c. if it then instantteneous velocity remains same during b_c period.so instantteneous velocity is same at b &c.
 
if not then ans will AT B point

if they both do constant acc motion then &their acc is A
 
then    time t=root(D / A)
for p it meet q at D/2 as they both do con acc
THEIR u=0 so from D/2=ut+1/2 At^2
 
                             D/2=1/2 At^2
                            
                              t=root(D / A)
