Sana remembers that her uncle’s visit was after 13th July but before 17th July, while her brother remembers that it was after 15th July but before 20th July. On which date of July was the visit?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 16
Both memories are true, so the visit must be a date that appears in both lists. “After” and “before” leave out the dates named.
Sana: after 13 and before 17, so 14, 15 or 16
Her brother: after 15 and before 20, so 16, 17, 18 or 19
The only date in both lists is 16th July
