August 13, 2003
The question for the day is from the topic of Races.
 Three runners A, B and C run a race, with runner A finishing 12 meters ahead of runner B and
18 meters ahead of runner C, while runner B finishes 8 meters ahead of runner C. Each runner travels the entire distance at a constant speed.
What was the length of the race?
(1) 
36 meters 
 
(2) 
48 meters 
(3) 
60 meters 
 
(4) 
72 meters 
Correct Answer  (2)
Solution:
Go from answer choices
Let the race be of length 48 meters
So when A runs 48m B run 36m and C runs 30m
Ratio of distance covered by B : C = 6 : 5
So when B covers 48m C would have covered 40m => B can give C a start of 8m.
