In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by:

A. 22.75 m
B. 25 m
C. 19.5 m
D. 53/7 m

• B. 25 m
  
  when A moves 200 M, B moves 169 M and C moves 182 M.
  
  So when C moves 350 M, B will move 169*350/182 = 325 M
  
  so C will beat B ( in race of 350 M) by 25 M ... option B

• A:B=200:169
  A:C=200:182
  C/B=C/A*A/B=182/200*200/169
  =182:169
  WHEN C COVERS 182M, B COVERS 169 M
  WHEN C COVERS 350M,B COVERS 169/182*350
  =325M
  SO C BEATS BY (350-325)=25M

• A. 22.75 m
  when In 200 hundred race when A has covered 200 m then B covered 169m and C covered 182m. It means C beat B in 182 m race by 13 m(182m-169m)
  
  So if there is 350 m race between C & B only. So when C will cover 350 m then B will cover 169*350/182 = 325 m
  so C will beat B in the race of 350 m by 25 m.

• B. 25 m
  when In 200 hundred race when A has covered 200 m then B covered 169m and C covered 182m. It means C beat B in 182 m race by 13 m(182m-169m)
  
  So if there is 350 m race between C & B only. So when C will cover 350 m then B will cover 169*350/182 = 325 m
  so C will beat B in the race of 350 m by 25 m.
