Huh?: Aarohi says that her uncle visited them after the 13th but before the 18th of month, while Neetu says that uncle had visited them after the 16th but before the 20th. If both are correct, on which date did uncle visit Aarohi and Neetu?

Given, Aarochi  remembers that his uncle had visited them after 13th, but before 18th of a month.

So, according to Aarochi his uncle came at either of 14th, 15th, 16th or 17th of the month.

Now, Neetu  remembers that Aarochi's uncle had visited them after 16th but before 19th i.e., either on 17th or 18th.

From the date mentioned by both there is only one date which is common i.e., 17th.

Hence, Aarochi's uncle visited at 17th of the month.

Their uncle visit them on 17th.

Step-by-step explanation:

according to Aarohi:

dates: 14, 15, 16, 17

according to Neetu:

dates: 17, 18 , 19

We can see 17 is the most common and falls under both person's day.
