\(x_1+x_2+x_3=24\) में \(0\leq x_i\leq8\) हो, तो valid count किस expression से मिलेगा?
If \(x_1+x_2+x_3=24\) and \(0\leq x_i\leq8\), which expression gives the valid count?
Explanation opens after your attempt
B. (1)
Concept
Since the total is (24) and the maximum of each of the three variables is (8), only ((8,8,8)) is possible. In exams check extreme feasibility before inclusion-exclusion.
Why this answer is correct
The correct answer is B. (1). Since the total is (24) and the maximum of each of the three variables is (8), only ((8,8,8)) is possible. In exams check extreme feasibility before inclusion-exclusion.
Exam Tip
कुल (24) और तीन variables की maximum (8) होने से केवल ((8,8,8)) संभव है। परीक्षा में inclusion-exclusion से पहले extreme feasibility देखें।
