In a 200 m race, A beats B by 20 m and c by 38m. In a race of 600 m B will beat C by

a) 20 m
b) 30 m
c) 25 m
d) 15 m

• It means, when A covers 200 m,
  B covers only (200-20)=180 m
  
  and C covers only (200-38)=162 m
  
  => When C covers 162 m, B covers 180 m
  
  => When B covers 600 m, C covers 162/180×600 = 540 m
  
  Hence, B beats C by 600-540 = 60 metre

• Answer 30
  From condition at the time of A completion b was at180 c was at 162
  While b have to complete 600race then c complete by only 570 so the difference is 30

• A : B = 200 : 180.
  
  A : C = 200 : 162.
  
  B:C= 180 : 162
  When B runs 10 m, C runs 9 m.
  
  When B runs 600 m, C runs = (9 x 600) / 10 = 540 m.
  
  B beats C by (600 - 540) m = 60 m.
