we can say that,
total time took by A =10 min
total time took by B =15 min
so
they will meet again at LCM (10, 15)
which is 30 min so they will meet after every 30 min.
hope it helps you if yes then please mark my answer as brainliest ☺️☺️

Ans: in 30 minutes both will be at O.
Because, A :: 1st round - 9th min, 2nd round - 19th min, 3rd round - 29th, 4th-30min about to start.
B :: 1st round - 13th min, 2nd round - 28th min, 3rd round - 30min about to start.
