DThursday
Correct Answer: SundayYour Answer: B
Explanation
Correct answer: Option B — Sunday. Counting total odd days up to this date, or using a verified Gregorian calendar calculation, gives weekday index 6 where Monday is 0; therefore the day is Sunday. Option A (Monday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (Tuesday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (Thursday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.
Important Notes
- Read the complete condition before calculating and write the required reference point, date, or clock time separately. This prevents a correct calculation from answering the reverse question.
- Keep units consistent. Reduce day differences modulo 7; treat 12 on a clock as zero for angle work; and convert gained or lost minutes into the same time unit as the stated interval.
- Verify the result independently. For calendar problems, move forward or backward by the remainder after division by
