Correct Answer - Option 3 : Friday
Given:
Today, the day on which Japan's FM reached India is Tuesday.
First, we will find number of odd days in these 45 days.
(45 ÷ 7) = 3 (Remainder)
Thus, odd days in these 45 days = 3.
Thus, the day when India's FM will go to japan: Tuesday + 3 odd days i.e. Friday.
Hence, Friday is correct.
