In 2mints A covers dist=2v unit and B covers dist=4v unit.
Total dist become they covers =4v+2v=6v unit.
Total perimeter=6v+6v=12v.
Combining speed of A and B is v+2v=3v.
Time=12v/3v=4 mints.
Ans:d.4 mints.

A is standing at one end of diameter of circle and B is standing anotherend of diameter in circle...
speed of A ix v and speed of B is 2v that means if A travels 1/2 parameter of circle then covers a total round of circle.If in 2min they meet each other then after 1min A will cover 1/2of the parameter of circle and and B will complete full circle after another 1 min A will cover full circle and B wil again cover the full circle...so ans is 2min
after 2min they will meet each other again
Ans 2min
