arithmetic
Enter the number that applies to the following □.
I decided to apply for the sweepstakes by preaching the quiz with three people. First, Mr. A solved 6 more questions than 1/3 of the total, and then Mr. B solved 10 less questions than the remaining 3/4. However, the third person, Mr. C, was able to solve only two-thirds of the remaining problems, so Mr. A solved the last eight questions and applied. This quiz has □ questions in all, of which Mr. A answered □ questions.
Arithmetic answer
(In total) 93 questions, (Mr. A) 45 questions
<Explanation>
* This problem is a considerable calculation. Make good use of the line segment diagram.
The last 8 questions that Mr. A solved are 1/3 of the problems left for Mr. C, so
8 × 3/1 = 24 is the problem left for Mr. C.
The problem solved by Mr. B is (24-10) x 4/1 = 56, which is the problem left for Mr. B.
The total number of questions is (56 + 6) x 3/2 = 93
The problem solved by Mr. A is 93 x 1/3 + 6 + 8 = 45.
