i think u are not getting my command, what is asked for is majority common free time on the work days. for example - on Friday only 4 people has class time. Kayes has class from 10:30 AM to 11:30 AM, Bishal Dutta Swapno has class from 10:30 AM to 11:30 AM, Sahria Bin Salam has class from 09:30 AM to 10:30 AM and from 11:30 AM to 12:30 PM, Salman Jubayer Tonmoy has class from 10:30 AM to 11:30 AM, here their common free time would be from 12:30 PM to 4 PM(note that 4pm is the ending time). you have to make a group of these four people and give me a data sheet of their common free time of the day of the week that contains their name, team name and free time slot
