Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:

A. 2 : 5 B. 3 : 5
C. 4 : 5 D. 6 : 7

• first number:120x/100
  second number:150x/100
  ratio of two numbers=120x/100:150x/100
  =4:5

• Look the sequence carefully
  4 2 4 8 6 8 4 16
  its like 4 2 4 add 2 then substract 2
  similarly next 4 8 6 add 4 then substract 4
  next 6 8 4 add 2 then substract 2
  next pattern 4 16 4 add 12 then substract 12
  
  so ans will be 4

• ans is 32
  
  (4 2 4 8 6 ) (8 4 16)
  4/2 = 2 ,2*2 =4,4*2=8,8-2=6
  8/2 = 4, 4*4 =16, 16*2 = 32

• 4,2,4
  8,6,8
  4,16,?(4=ans)

• Let the number be 100x
  Hence 20% and 50% so the ratio will be
  120x : 150x = 4 : 5

• ans is 4
  4-2=2,2+2=4
  8-6=2,6+2=8
  4+12=16,16-12=4

• kritika its very simple 4 2 4 subtract 2 & add 2
  8 6 8 sbtrct 2 add 2
  4 16 _ 4 will be the answer bcz upto now there is a no. betwn same no.s so 4 will comes

• (4,2,4,8,6)(8,4,16,x,y)
  1st+3rd=4th ==> 4+4=8
  1st+2nd=4th ==> 4+2=6
  so, x=8+16=24
  y=8+4=12

• 4 2 4
  8 2*2+2=6 8
  4 6*2+4=16 4
  8 16*2+6=38 8,may be,
  
  so series may be 4 2 4 8 6 8 4 16 4 8 38 8.......

• Let the third number be x.
  
  Then, first number = 120% of x = 120x = 6x
  100 5
  Second number = 150% of x = 150x = 3x
  100 2
  Ratio of first two numbers = 6x : 3x = 12x : 15x = 4 : 5.
  5 2
