The ratio of the present ages of Ram and Rahim is 3 : 2. The ratio of the present ages of Rahim and Aman is 5 : 2. What is the ratio of the present ages of Ram and Aman?
(a) 4 : 15
(b) 15 : 4
(c) 9 : 5
(d) Cannot be determined
(e) None of these

• ram/rahim=3/2 -----(1)
  rahim/aman=5/2---------(2)
  (1)x(2)= ram/aman=3/2x5/2=15/4

• ram/rahim=3/2;
  rahim/aman=5/2;
  rahim=5aman/2;
  ram/(5aman/2)=3/2;
  ram=(3/2)*5aman/2;
  ram/aman = (3/2)*5/2;
  ram/aman = 15/4;
  option b

• ram=3*5.
  rahim=2*2.
  aman=5*2.
  therefore ratio =15:4.

• ram:rahim=3:2
  rahim:amin=5:2
  ram:rahim:amin=5(3:2):2(5:2)=15:10:4
  ram:amin=15:4

• ram: rahim=3:2
  rahim:aman = 5:2
  making ratios equal
  for that
  ram: rahim:aman
  1)3:2: (?)
  2)(?) : 5:2
  
  now as rahim's age ratio increased from 2 to 5
  so to get ram's age ratio respect to that is 7.5
  so ram:aman = 7.5:2 = 15:4

• Option B.
  Ram : Rahim=3:2
  Let Ram's present age be 3x and Rahim's present age be 2x.
  
  Now, Rahim : Aman = 5:2
  Here let Rahim's present age be 5y and that of Aman be 2y.
  
  comparing Rahim's present age in the statements given above.
  2x=5y
  ==> x/y=5/2
  
  Now, ratio of present ages of Ram and Aman are
  Ram: Aman= (3*5):(2*2)= 15:4

• Ram:rahim::rahim:aman
  3 : 2 :: 5 : 2
  (3:2)*5=15:10
  (5:2)*2=10:4
  Now ram=15 & aman=4

• ram/rahim=3/2
  rahim/aman=5/2
  to get ram/aman directly multiply them
  3/2 * 5/2 = 15/4
• 7 years agoHelpfull: Yes(1) No(0)
• ram/rahim=3/2
  rahim/aman=5/2
  to get ram/aman directly multiply them
  3/2 * 5/2 = 15/4

• answer is b) 15 : 4
  solution is:-
  given-
  
  ram : rahim=3:2
  therefore, rahim= 2/3 ram----------1
  
  rahim : aman=5:2
  therefore, rahim=5/2 aman----------2
  
  from 1 and 2 equations,
  2/3 ram=5/2 aman
  hence, ram/aman = (5/2) * (3/2)=15/4 or 15:4

• Ram/rather=3/2. Rahim/Alan=5/2. So second condition implies that rahim=5/2 times of aman..so substitute the value of rahim in condition1 ..so that becomes ram/aman=15/4
