33
16

• I think the question is wrong...!!!!!

• for Even places x/2 from the start
  for Odd places x/3 from the end
  
  EVEN places ODD Places
  ----------- ----------
  48/2 = 24 90/3 = 30
  24/2 = 12 30/3 = 10
  
• 10 years agoHelpfull: Yes(10) No(2)
• c)33
  because in the series all no.s divisible by 3 and
  in d options 33 is the only option divisible by 3.

• 3 ? 30 90
  all that multiby 3
  that and that no ans that 9
  and that
  10
  ans 10

• moving from right to left alternatively and starting from 90:
  90/3=30
  30/3=10
  10/3=3
  ans=3

• Answer 10
  
  3Rd no get it divided for 1st no by 2 for 48.
  
  5th no get it divided for 3rd no by 2 for 24.
  
  6th no get it multiple for 3 for the 4th no for 30
  
  so 4th no is multiple for 3 for the 2nd no for 10
  
  
  so answer 10

• 3*10=30
  3*30=90
  answer : 10
• 10 years agoHelpfull: Yes(3) No(0)
• 33 is the ans... bcz it is a multiple of 3
• 9 years agoHelpfull: Yes(2) No(1)
• 10 is the ans.
• 10 years agoHelpfull: Yes(1) No(0)
• All numbers are divisible by three except 33.
• 10 years agoHelpfull: Yes(1) No(8)
• The alternative numbers are decreasing/increasing from left to right
  odd ones are decreasing by 1/3 and even ones are increasing as their double
  so 90/3=30
  30/3=10
• 10 years agoHelpfull: Yes(1) No(0)
• second sequence 48 24 12 i.e.., 48/2 =24 and 24/2 =12.
  first aequence 3 ? 30 90
  we get 3*10=30 and 3*30= 90 therfore ans is 10.
• 10 years agoHelpfull: Yes(1) No(0)
• two series present
  3,?,30,90
  48,24,12
  
  90/3=30 ,30/3=10 ,10/3=3.33 round 3
• 10 years agoHelpfull: Yes(1) No(0)
• ans is 10
  Given series contains two series
  3 , ? , 30 , 90
  and
  48 , 24 , 12
  first series is multiple of 3 ie (3) , (3*3) , (10*3) , (30*3) but 9 is not in option and we to select one to we go for 10
  
  second series is decreasing by x/2
• 8 years agoHelpfull: Yes(1) No(1)
• 90/3=30
  30/3=10
• 8 years agoHelpfull: Yes(1) No(1)
• ans -10
  3*3+3^0=10
  9*3+3^1=30
  27*3+3^2=90
  and so on...............so ans will be 10.
• 10 years agoHelpfull: Yes(0) No(0)
• ans=10 because.................
