If 19 October 2010 was Tuesday, what day was it 826 days before?

Correct answer: Option B — Tuesday. 826 = 118 complete weeks + 0 days. Moving before by 0 day(s) from Tuesday gives Tuesday. Option A (Wednesday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option C (Thursday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error. Option D (Saturday) is rejected because it does not equal the computed result; it represents a counting, direction, leap-year, interval, or hand-motion error.
