• Here 8 possibilities is the right option because,first we take +ve conditions(2,3,5) and then -ve conditions(1,4).m possible only once.In 3 rd condition B fixed to one position.in the same condition S,R can vary in 2 positions.A can give in one position and also police in between a&R also one position.In 1st condition for AK,G we can arrange 2 positions(AK,G)(G,Ak).finally Police can arrange in 2 positions.assume this as one by one for given pattern.P,S,B,R,P,A,AK,M,G,P.so,1*1*2*1*2*2.
  so,final ans is 8

• There are 8 combinations possible.
  Combination=Selection
  
  Let us first eliminate the positions Arvind and G cannot occupy.
  These will be 1,8,9 and 10.
  1 and 10 due to the 1st condition
  8 and 9 due to the 4th and 2nd conditions respectively
  
  S-B-R can occupy only 3 consecutive positions.
  This can be 1-2-3, 2-3-4, 3-4-5, 4-5-6, 5-6-7 or 6-7-8
  
  If we select 1-2-3, the 4th position becomes unavailable for Arvind/G owing to condition 4. Now, 3 positions available(5,6,7) for 2 ministers Arvind and G. This will be 3C2=3
  
  If we select 2-3-4, the 5th position becomes unavailable for Arvind/G. Now, only 2 positions(6,7) available for 2 ministers. This will be 2C2=1
  
  If we select 3-4-5, the 2nd and 6th positions become unavailable. Now only 1 position(7) available for 2 ministers.
  Similarly, for 4-5-6, the 3rd and 7th positions become unavailable. Now also only 1 position(2) available for 2 ministers.
  
  If we select 5-6-7, the 4th position becomes unavailable for Arvind/G. Now, only 2 positions(2,3) available for 2 ministers. This will be 2C2=1
  
  If we select 6-7-8, 5th position becomes unavailable. Now 3 positions(2,3,4) available for Arvind/G. This will be 3C2=3
  
  Thus, the total number of combinations=3C2+2C2+2C2+3C2=3+1+1+3=8

  3) S, B, R, P, G, P, AK, P, M, P.

  8) P, G, P, AK, P, R, B, S, M, P.
  and only 2 satisfy condition five 1 & 8 so answer is 2.

  bcz according to 5th condition there is always one policemn between a and r.
• 9 years agoHelpfull: Yes(0) No(1)
• there is only 1 possibility
  S D R P AK P G P M P because there shd be only 1 policeman between ak and r..... all other possibilities violates this rule
• 9 years agoHelpfull: Yes(0) No(1)
• There are 4 options possible ,
  according to point 5 there could be only one police between Ak and R, and according to 3 SBR will be one after another and their order could change in two ways. one more point we have to focus that their must be one police adjacent to Ak and G both so here is the arrangements given below
  
  
  P G P AK P R B S M P
  P G P Ak P R S B M P
  these two arrangements given above by changing the order of rbs and rsb.by maintaining (Ak P R) same on both
  S B R P AK P G P M P
  B S R P AK P G P M P
  again by changing the order of SBR and BSR but (AK P R)would be same
  
  
  P G P AK P R B S M P
  P G P Ak P R S B M P
  S B R P AK P G P M P
  B S R P AK P G P M P 4 arrangement according to me :)

  These will be 1,8,9 and 10.
  1 and 10 due to the 1st condition , 8 and 9 due to the 4th and 2nd conditions respectively.

  If we select 2-3-4, the 5th position becomes unavailable for Arvind or G. Now, only 2 positions(6,7) available for 2 ministers. This will be 2C2=1.
  If we select 3-4-5, the 2nd and 6th positions become unavailable. Now only 1 position (7) available for 2 ministers. Similarly, for 4-5-6, the 3rd and 7th positions become unavailable. Now also only 1 position (2) available for 2 ministers.
  If we select 5-6-7, the 4th position becomes unavailable for Arvind or G. Now, only 2 positions(2,3) available for 2 ministers. This will be 2C2=1.
  If we select 6-7-8, 5th position becomes unavailable. Now 3 positions(2,3,4) available for Arvind/G. This will be 3C2=3.
  Thus, the total number of combinations=3C2 +2C2 +2C2+3C2 = 3 + 1 + 1 + 3 = 8.
