QUESTION #7951
Question 1
\(9999 + 8888 + 777 + ? = 19700\). Find the missing number.
Correct Answer Explanation
\(9999 + 8888 + 777 = 19664\)
\(19700 - 19664 = 36\)... but answer key gives D (26). Let us recheck: \(9999 + 8888 = 18887\), \(18887 + 777 = 19664\), \(19700 - 19664 = 36\). Answer should be 36 (option A). Students should verify arithmetic carefully.
