Answer:80 minutes
Step-by-step explanation:
Time taken by shikha to drive one round of the field= 20minutes
Time taken by Ravi to drive one round of the field= 16 minutes
The LCM of 20 and 16 gives the exact number of minutes after which they will meet at the starting point again
Now,
20=2*2*5
16=2*2*2*2
LCM = 2*2*2*2*5
=4*4*5
=16*5
=80 MINUTES
HENCE they will meet after 80 minutes at the starting point...
