Answer 2

Answer:

Pradeep visited Chennai on the 11th of July.

Step-by-step explanation:

Given that,

Pradeep remembers that he visited Chennai before the 12th of July but after the eighth of July.

Then, the probable dates are the 9th of July, the 10th of July, and the 11th of July.

If we make set A = (9, 10, 11)

His friend remembers Pradeep visited Chennai after the 10th of July and before the 14th of July.

Then, the Probable dates are the 11th of July, the 12th of July, and the 13th of July.

If we make set B = (11, 12, 13)

Find the day when Pradeep visited Chennai will be the intersection of the two sets A and B.

$A\cap B \\\\= (9,10,11)\cap (11,12,13)\\\\= (11)$

So, Pradeep visited Chennai on the 11th of July.
