Answer 1

The Correct Option is C

Step 1: Analyzing Statement III:
Deepali's 77th birthday was on June 3rd, 2018. So, Deepali's age on October 30th, 2018 = 77 years + (days from June 3 to Oct 30). But we need actual date difference for precise age. However, this establishes Deepali's birth year.

Step 2: Using Statement II:
Ananya is 29 years younger than Deepali. So, Ananya's age can be calculated from Deepali's age.

Step 3: Using Statement I:
Arnav is 6 years older than Ananya. So, Arnav's age can be calculated.
All three statements together provide sufficient information to calculate Arnav's age on October 30th, 2018.
