In a one km race A gives B a start of 100m and in a one km race B gives a start of 80 m to C. In a 1 km race who will win and by how much distance from the worst performer between two losers?  Choices
A) 172 m
B) 372 m
C) 172 m
D) 772 m
E) 632 m
Ratio of speeds of A:B = 1000:900 = 100:90   Ratio of speeds of B:C = 1000:920 = 100:92   Therefore, when A moves 1000m , B moves 900 m and when B moves 900m, C moves 828m   Thus,   Since , C moves 8 % less than B in the same time . Thus, C is the worst performer and 172 m will win by him by 172 m   172 mNSWER=172 m
