Correct answer: C. 72
Explanation
Let the second number be 6x; then first = 3x and third = 2x. Sum = 11x = 3 × 44 = 132, so x = 12. Numbers are 36, 72, 24; the largest is 72.माना दूसरी संख्या 6x है; तब पहली = 3x और तीसरी = 2x। योग = 11x = 3 × 44 = 132, अतः x = 12। संख्याएँ 36, 72, 24 हैं; सबसे बड़ी 72 है।More Mathematical Reasoning and Aptitude questions
