Multiple choice general knowledge math & puzzles If one-seventh of a number exceeds its eleventh part by 100 then the number is… 770 1100 1825 1925 Reveal answer Fill a bubble to check yourself D Correct answer Explanation Let the number be N. One-seventh exceeds one-eleventh by 100: N/7 - N/11 = 100. This gives (11N - 7N)/77 = 100, so 4N/77 = 100. Therefore N = 100 × 77/4 = 25 × 77 = 1925.
