If 15th August 1947 was a Friday, on what day of the week did India celebrate its first Republic Day on 26th January 1950?
Answer and explanation
Correct answer: A. Thursday
- Step 1: Days remaining in 1947: Aug (16) + Sep (30) + Oct (31) + Nov (30) + Dec (31) = 138 days.
- Step 2: 1948 (leap year) = 366 days; 1949 (ordinary year) = 365 days.
- Step 3: Days in Jan 1950 = 26 days.
- Step 4: Total days = 138 + 366 + 365 + 26 = 895 days.
- Step 5: 895 mod 7 = 6 odd days. Friday + 6 days = Thursday.
Why not the others: The remaining days of the week (Wednesday, Friday, Tuesday) arise from miscounting leap years, omitting century odd days, or making month-day remainder slips.
