Download Solution PDFदिया गया : 31 जनवरी 2009 शनिवार था
अब, 31 जनवरी 2009 से 31 जनवरी 2013 = 4 वर्ष।
और, 4 वर्षों में 1 लीप और 3 साधारण वर्ष होते हैं
अतः कुल विषम दिन = (1 × 2) + (3 × 1) = 2 + 3 = 5 विषम दिन।
अतः, 31 जनवरी 2013 = शनिवार + 5 = गुरूवार।
लेकिन, हमें 30 जनवरी 2013 का दिन ज्ञात करना है , इसलिए 31 जनवरी 2013 में से 1 दिन घटाना होगा।
अतः 30 जनवरी 2013 गुरूवार होगा - 1 = बुधवार।
अतः, "बुधवार" सही उत्तर है।
