In a race of 200 m. A can beat B by 15 m and C by 19 m then how much time C would take To beat B in the race of 3700 m ?

• In 200 race A:B=200/185 , A:C=200/181
  than in 3700m race B beats by C,3700- (181/185)*3700=80

• for 185m B leads C by 4m==> 3700/185=20
  20*4=80

• question is wrong..
  but if replace C by B in question part..
  ans would be 74 mt..
  as in this case C will lead B by 4 mt in every 200 mt..
  and for 3600 mt C take lead of 72 mt
  in last 100 C lead by 2 mt..
  therefore total lead is 74 mt..

• A:B:C=200:185:181
  we have to find C:B
  we can also write C:B as C/A * A/B which is equivalent to 181/200 * 200/185 which is equal to3620
  hence B beat C by 3700-3620=80m

• when A run for 200 m.
  B run 185 m only.
  c run 181 m only.
  according to condition given in que. c beat b which looks not possible...
  if b beat c then..
  when b run for 3700 c run for=181/185*3700=?
  so b beat c by=3700-?=answer

• I think question will be like this...
  in a race of 200 m. A can beat B by 19 m and C by 15 m then how much time C would take To beat B in the race of 3700
  for this questions answer will be 74 min ..

• Question is wrong.
  It would be How much time B would take to beat C ?
  A : B = 200 :185
  A : C = 200 :181
  B : C = 185/200 * 181/200
  B : C = 185 : 181
  When B covers 185 m , C covers 181 m.
  When B covers 3700 m, C covers (181/185)*3700 = 3620 m.
  Therefore, B beats C by (3700 - 3620) m = 80 m.

• for 200 m B lead C in 4 m
  Hece for 200*18.5=3700
  lead by 4 meter 4*18.5=74m

• B beats C by 80 mtr

• from given information we get:- Velocity of b(Vb) / Vc= 85/81
  
  now b run 3700m and let it beat c by x meter. than 3700 / (3700-x)= 85/81
  
  hence x= 174.11 m Ans.

• For 200 mt. race
  A -> B =15 mt.
  A -> C =19 mt.
  So, B -> C = 19-15 = 4 mt.
  since in 200 mt race B -> c =4 mt.
  therefore in 3700 mt. ------- = (4/200)*3700 = 74 mt. ans.

• Question is wrong.. it will be how much time B will beat C?
  
  Answer :
  80m

• Please explain your answer properly to make it approve?
  for 200 Metre
  a:b:c - 200:185:181
  using unitary method
  for 3700 M
  a:3700
  b : (185/200)*3700=3417.5 mtr
  c : (181/200)*3700=3348.5 mtr
  b - c = 3417.5 - 3348.5 = 69 mtr
  ans : 69

• wrong question
• 8 years agoHelpfull: Yes(0) No(1)
• C:B= 181/185; .......so 181/185*3700=20*181= 3620
  means B beats by C 3700-3620=80.
