Question from UPSC Prelims 2024 CSAT
Explanation :
Statement I Alone:
– Knowing only the size (12 MB) isn’t enough to find download time
– Need transfer rate to calculate time
Statement II Alone:
– Knowing only transfer rate (2.4 KB/s) isn’t enough
– Need file size to calculate time
Both Statements Together:
1. Convert 12 megabytes to kilobytes:
12 MB = 12 × 1024 = 12,288 KB
2. Calculate time:
Time = Size ÷ Rate
= 12,288 KB ÷ 2.4 KB/s
= 5,120 seconds
= 1 hour, 25 minutes, 20 seconds
