A beat B by 15 meters and C by 19 meters in 200 m race. then in the race of 3700 meters B will defeat C by how much distance ?

a. 38
b. 45
c. 74
d. 80

• In a (200-15)=185 meters race B defeat C by (19-15)=4 meters.
  so in 3700 meters B will defeat C by 4*3700/185=80 meters
• 10 years agoHelpfull: Yes(28) No(3)
• When B reaches to the final point then C will be 181*200/185 m behind.
  now applying unitary method we get: 3700*181/185= 3620
  thus B defeat C by 80 meters.

• 185/181=3700/x
  X=3620
  So, 3700-3620=80 ans

• Friends difference 4 meter is when B is 15 meter away from finish line, but B win only when comes at finish line.
  So 74 meter is completely wrong.

• look at distance covered by them
  
  A covered 200m
  B covered 185m
  C covered 181m
  
  now B covered 185m and C covered 181m ......so in the race of 185m B defeat C by 4 m
  
  hence in race of 3700 ... (4/185)3700 = 80 meter

• distance of A - distance of B = 15 meters //for 200 m race , given
  distance of A - distance of C = 19 meters // for 200 m race, given
  ( Va*t) - ( Vb*t ) = 15 //equation 1
  ( Va*t ) - ( Vc*t ) = 19 // equation 2
  
  so subtracting equation 1 from 2 , we get
  (Vb*t) - (Vc*t) = 4 meters
  which means the difference in distance of B and C will be a multiple of 4 always.
  and in the options given , only 80 is the multiple of 4, so ans in 80

• 80
  a/B=200/185
  a/c=200/181
  therefore b/c=185/181
  multiply both num and denom by 20
  b/c=3700/3620
  therefore diff is 80

• B beating C by 4m
  
  3700/200=18.5
  18.5*4= 74.

• From R.S. Aggrawal
  If A is at 200m then B=200-15=185m
  and
  C=200-19=181m
  Therefore,
  When B is at 3700 then
  C=(181/185)X3700=3620
  Ans=80

• a=200,b=185,C=181
  b beat c by 4 meter in 200 meter race
  then in 3700 meter race =4*2/200=74 meter
• 10 years agoHelpfull: Yes(1) No(3)
• in 200 meters when a runs 200 m then b runs 185m and c runs 181m so in 200 m the difference in their distance is 4m.. i.e 4 m in 200 meter so in 100 meter it will be 2 meter. now 100*37 = 3700 meter and therefore 2*37 = 74. ans

• Dif between B & C = 19-15=4m
  then in 3700m race B will defeat C by (4*3700)/200=74m
• 10 years agoHelpfull: Yes(1) No(2)
• when A=200m then B=200-15=185 & c=200-19=181
  B-C=185-181=4
  B beat C by=(4/185)*3700=80m

• for every 100 meters B is 2 m away.
  so for 3700 m B beat C by 37*2=74 m
  ans:c
• 10 years agoHelpfull: Yes(0) No(1)
• Difference between B and C is 4meters.
  For 200meters the difference is 4meters than for 3700meters the difference is
  (4*3700)/200= 74meters.
• 10 years agoHelpfull: Yes(0) No(1)
• In 200m race b is 4 m ahead c. so in 3700 m race
  (3700/200)*4 m ahead = 74 m ahead

• b's caliber in 200mts race 185/200 , c's caliber in 200mts race 181/200 ,b's caliber in 3700mts race.. 185/200*3700=3422.5 , c's caliber in 3700 mts race ..181/200*3700=3348.5 so 3422.5-3348.5 = 74
• 10 years agoHelpfull: Yes(0) No(1)
• The answer should be 80.because when a run 200meters.then b run 185m and c run 181 m.so when b run 185 than c run 181.so when b run 3700m than c should run 3620.so b beat c 80m

• In 200m
  Let B covers x m.
  So,in 400 B will cover 2x m.
  Similarly in 3700 m B wil cover (37x/2)m.
  Let C covers y m in 200m race.
  So,in 3700 m race C will cover (37y/2)m.
  From Questn..
  x+15=200 & y+19=200
  =>x=185 & y=181
  distance between B & C=(37*x)/2-(37*y)/2
  Substituting x &y
  distance=74m.

• from given data, A,B,C has covered 200m,(200-15)=185m,(200-19)=181m respectively. Here B defeat c by (185-181)=4m using unitary method, 185:4::3700:? (3700*4)/185=80m
