RAS question
India's Republic Day (26th January) fell on a Thursday in 2023. On which day did India's Independence Day (15th August) fall in 2023?
Correct answer: (A) Tuesday.
India's Independence Day, 15 August, fell on a Tuesday in 2023.
Explanation
Republic Day, 26 January 2023, was a Thursday. Counting forward to 15 August gives 201 days: 5 remaining days in January, then 28 in February, 31 in March, 30 in April, 31 in May, 30 in June, 31 in July, and 15 days in August. Since 201 equals 28 complete weeks plus 5 odd days, the weekday moves five steps ahead from Thursday: Friday, Saturday, Sunday, Monday, Tuesday. The Embassy of India in Belgrade notice for the Independence Day ceremony also lists the event as being held on Tuesday, 15 August 2023, confirming the result.
Why the other options are wrong
- (B) Monday would be only four odd days after Thursday, but the interval from 26 January to 15 August 2023 has five odd days.
- (C) Wednesday would require six odd days after Thursday, whereas the 201-day interval leaves a remainder of five days after complete weeks.
- (D) Thursday would mean zero odd days after complete weeks, but 201 days equals 28 weeks plus 5 odd days.
Concept
Calendar reasoning through odd days is a standard mental ability concept in RAS because it checks precise counting across months. Aspirants must anchor a known weekday and move through a date interval without relying on memorisation.
