Q. In a kilometer race, A beats B by 200 mtr and C by 360 mtr.In a race of 500 mtr by how many meters does B beat C ?

Option
a) 80
b) 200
c) 100
d) 160

• when a completes 1000m
  B completes 800m
  c completes 640m
  when B completes 500 m thn c completes 500*640/800=400
  hence when b covers the 500m race then c is at 400m
  So,b beats c by 100m

• A:B = 1000/800 ; C:B = 1000/640;
  A:B / A:C = A/B * C/A = 4/5
  4/5 * 500 =400
  So C runs 400 meter when B runs 500m
  ans 500-400=100m
  ans =100 m

• When A completes 1000m, B completed (1000-200=) 800m and C completed (1000-360=)640 litres.
  
  In the time B covers 800 m , C ios covering 640 m
  In the time B covers 1000 m, C covers 640*1000/800 = 800 m
  
  So, B beats C by 200 m.
  
  Answer is 200 m.

• a=>1000m
  b=>1000-200=800m
  c=>640m
  so when b completes 800m c finishes 640m
  i.e when b covers 500m then c covers=(640/800)*500=80 meters.

  when B completes 500 m thn c completes 500*640/800=400
  hence when b covers the 500m race then c is at 400m
  So,b beats c by 100m
