Correct answer: D. 20
Explanation
1024 = 2¹⁰, so the population must double 10 times. Each doubling takes 2 minutes, therefore the total time = 10 × 2 = 20 minutes.1024 = 2¹⁰, अतः संख्या को 10 बार दुगुना होना होगा। प्रत्येक दुगुनीकरण में 2 मिनट लगते हैं, अतः कुल समय = 10 × 2 = 20 मिनट।More Mathematical Reasoning and Aptitude questions
