Blog Post #73 - Identify the approach to this day to day puzzle!


This week's blog came out of an offline discussion with my school friend A Ramananda Pai on a simple Maths problem... Thought of documenting that as a simple blog here primarily to understand how we along with our kids approach the solution and also to drive home the message that whatever we study, always has an application somewhere or the other :)
All along we always wonder why we study certain topics when they may not be of any use and this is a good simple example of how we can put something that we studies during school to real use!

Two people A and B go around a circle and cover a distance of 300 metres during every revolution. Both of them start at the same point and A takes 4 mins to complete 1 round while B takes 7 mins to complete the same round. After how many rounds, will they pass each other again (assume they both clock the same average speed throughout this exercise)

More than the actual answer, remember I am looking for the approach to the solution
