In a100m race A beats B by 25m B beats C by 4 then A beats C by

• A : B = 100 : 75
  
  B : C = 100 : 96.
  
  A : C = (A/B x B/C) = (100/75 x 100/96) = 100/72 = 100 : 72.
  
  A beats C by (100 - 72) m = 28 m.

• Ans : 28m
  Speed of A with respect to B : 100/75B
  Speed of B with respect to C : 100/96C
  Speed of A with respect to C : 100*100/75*96=100/72 .
  So A beats C by 100-72=28m.
