To find the required number of days, We need to find the L.C.M. of 64 and 72
Now, The L.C.M. of 64 and 72 = 576

Therefore, They both will meet again after 576 days

Sudhir goes to the market once every 64 days and Sushil goes to the same market once every 72 days. They met each other one day. How many days later will they meet each other again?
