उत्तर और व्याख्या · explanation in English
Answer: (c) 12 जुलाई को रविवार है यदि वर्ष एक अधिवर्ष है।
From 12 January to 12 July is 181 days in an ordinary year and 182 days in a leap year. 182 is exactly 26 weeks, so in a leap year 12 July falls on the same day, Sunday.
- Days from 12 January to 12 July: January 31, February 28 or 29, March 31, April 30, May 31, June 30.
- Ordinary year: 181 days = 25 weeks + 6 days, so 12 July is Saturday.
- Leap year: 182 days = 26 weeks exactly, so 12 July is Sunday.
- 15 July is then Tuesday (ordinary year) or Wednesday (leap year), never Sunday — (a), (b) and (d) fail.
Remember · Count days between the two dates and divide by 7; the remainder is the number of weekdays to move forward.
