एक CD में 12 संगीत ट्रैक हैं जिनकी लंबाई (मिनट में) है: 3, 7, 4, 3, 5, 6, 4, 5, 4, 7, 8, 8 और संगीत के प्रत्येक मिनट के लिए 12 MB भंडारण चाहिए।
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: C. 768 MB of memory is used for the 12 music tracks.12 संगीत ट्रैकों के लिए 768 MB मेमोरी प्रयुक्त होती है।
Explanation
Total length = 3+7+4+3+5+6+4+5+4+7+8+8 = 64 minutes; storage = 64 × 12 = 768 MB. A 90% reduction would leave 76.8 MB, not 69.12 MB, so option 4 is false.कुल अवधि = 3+7+4+3+5+6+4+5+4+7+8+8 = 64 मिनट; भंडारण = 64 × 12 = 768 MB। 90% कमी के बाद 76.8 MB बचेगा, 69.12 MB नहीं, अतः विकल्प 4 असत्य है।More Information and Communication Technology (ICT) questions
