Subita remembers her sister's birthday is after 5 February but before 8 February whereas her brother Raghu remembers that his sister's birthday is after 6 February but before 9 February. On which date of February is Subita's sister's birthday? Correct Answer 7 February

The logic followed is:

According to Subita's memory, her sister's birthday is after 5 February but before 8 February means either on 6 February or (7th February).
