Soham and Banni drive one round of the field in same point, same time and same direction.
So, they will meet again after LCM of both values at the starting point.
LCM:
18=2*3*3
12=2*2*3
LCM=2*3*3*2=36 minutes (Answer)

Answer = 36 minute
Time taken
By Soham = 12 minutes
Time taken
By Baani = 18 minute
Speed of
Soham = distance / time
= 2πr / 12
Speed of
Baani = 2πr / 18
Substract
Their speed = 2πr[ (1/12 ) - ( 1/18)]
= 2πr[ 1 / 36]
= 2π r[ 1 / 2 × 18]
= πr / 18
Time taken
To catch up = distance / velocity
= 2πr / πr / 18
= 2 × 18
= 36 minute
