| When we took ratio between 100:90 we get 10. So they took 90 insted of 10. I hope you understand. |

100-10=90, 100-28=72;
Because according to question A can gives B 10m and A can gives C 28m. I try my best to solve your problem. |

| Why not going the race at which the question says? That is when finish the game B is 18m ahead of C. |

| Because it is same race. They must complete same distance so when B has completed 100 m. He will give C 20m. |
