Q.4

Three friends Mukesh, Rajesh and Chetan walk from point A to B which are the two ends of the diameter of a semi circular park. Mukesh takes the shortest path along the diameter whereas Chetan takes the longest path which is along the periphery and Rajesh walks along two straight lines AC and CB where C is a point on the periphery of the semi circular park such that AC + CB is maximum possible length. If all three reach B simultaneously, then what is the ratio of speeds of Mukesh, Rajesh and Chetan respectively?

  • 2 : 2*root(2) : pi
  • 2*root(2) : 2 : pi
  • root(2) * pi  : pi : root(2)
     
  • pi : 2 * root(2) : 2
  • 2:22:π
