in a 100m race ,b bet c by 25m.a bet b by 20m.then a will beat c by what metres

• A:B=100:80 AND B:C=100:75
  A:C=(A/B)*(B/C)=100/60
  A WILL BEAT C BY 100-60=40M

• A:B=100:80 AND B:C=100:75
  A:C=(A/B)*(B/C)=100/60
  A WILL BEAT C BY 100-60=40M

• A:B=100:80
  B:C=100:75
  so
  we want A:C then
  B must be in 80.
  
  100 ---> 80
  75 ----> x
  x=60
  
  so B:C will be 80:60
  
  then A:C is 100:60 means A beat C by 40m.

• b/c=100/(100-25)=4/3
  a/b=100/(100-20)=5/4
  a/c=(a/b)*(b/c)=5/3=100/60
  so a beat c by (100-60)=40m

• 60 m
  100m B = 75m C
  100m A = 80m B
  now 80m B = (75*80)/100 = 60m C
  hence 100m A = 60m C
  therefore A beats C by 100-60 = 40 m

• given b:c=100:75=4:3 and a:b=100:80=5:4
  i.e., a:b:c=20:16:12
  so in 20mts race if a runs 20 mt then c runs by 12
  then in 100 mt 100:80:60
  so ans is 40

• a:b=100:80=5:4
  b:c=100:75=4:3
  a:b:c=20:16:12
  for 20m->8m(difference)
  then for 100m->?
  it is 40m

• A:B=100:80 AND B:C=100:75
  A:C=(A/B)*(B/C)=100/60
  ans=100-60=40M

• 45. c----25---b then b------20-----a.so the total distance is 45

• let c traveled x m and b traveled x+25m and a traveled x+25+20m
  so,x+x+25+x+25+20=100
  3x+70=100
  x=10m
  so A travels 55 m and C travels 10m
  so a beats c by 45 m

• 36 meters
  a beats b by 20 percentage
  20 percentage of 80 is 16 so c is at 64 metrs
  100-64 = 36 meters

• for a to complete the race he need to run 100m
  a beat b by 20m so b run 80m
  b beat c by 25m so c run 55m
  so, a beat c by 45m

• A B
  100 80
  ----------------------
  B C
  100-----------> 75
  10-----------> 7.5
  8X10------------>8X7.5
  80 --------------->60
  ---------------------------
  A B C
  100 80 60

• A BEATS B BY 20MTR B BEATS C BY 25 METRE
  A B B C
  100 80 100 75
  80 75/100*80
  80 60
  therefore the ratio of A B C is 100:80:60
  hence A beats C by 40 mtr
