A rabbit, a tortoise and a mongoose decide to run a closed circuit race. If the rabbit overtakes the mongoose 2 times per round, with the 2nd overtake being at the starting point and the mongoose overtakes the tortoise 4 times per round the 4th overtake being at the starting point, then find the ratio of the speed of the rabbit to that of the tortoise.
a) 15 : 1 b) 8 : 1 c) 6 : 1 d) 10 : 1

• Ratio of speed of rabbit and mongooe=2:1
  Ratio of speed of Mongoos and tortoise=4:1
  Ratio of speeds of Rabbit,Mongoos and tortoise=8:4:1
  
  Ratio of Rabbit and Tortoise=8:1

• since the rabbit overtakes the mongoose 2 times, the rabbit speed is 3 times the speed of tortoise and similarly the mongoose speed is 5 times the speed of tortoise. So the ratio of speed of the rabbit to that of the tortoise is 15:1
