• Prof. cyclist takes 4 mins to complete a lap.
  Novice takes 6 mins to complete a lap.
  Prof. cyclist takes 4 mins for 1st lap, 8 mins for 2 laps, 12 mins for 3 laps and so on.
  Similarly, novice takes 6mins for the 1st lap, 12mins for 2 laps, 18mins for 3 laps and so on.
  So they both meet at the starting point at the 12th min again.
  
  simply the ans is LCM of 4 & 6
