Meena correctly remember that her father's birthday is after 18th May but before 22nd May. Her brother correctly remembers that their father's birthday is before 24th May but after 20th May . On which date in May was definitely their father's birthday ?
Cannot be determined
None of these
Correct Option: E
Days by Menna, 19th, 20th or 21st May. Days by her brother, 21st , 22nd or 23rd May. Clearly, 21st may is common in both the groups and hence it is the required day.
