Match List I (Statement) with List II (Value) and choose the correct answer from the options given below.
List I
i.Base-10 (denary) value of the binary number 100000
ii.The number of seconds an internet service provider advertising a download speed of 80 megabits per second takes to download an 80-megabyte file
iii.A music file is 80 megabytes; MP3 compression reduces its size by 90 percent; the number of such compressed files that can be stored on an 800 MB CD
iv.The denary (base-10) equivalent of the hexadecimal digit E
List II
a.100
b.14
c.32
d.8
Ai-b, ii-d, iii-a, iv-c
Bi-c, ii-d, iii-a, iv-b ✓ Correct
Ci-a, ii-b, iii-d, iv-c
Di-c, ii-a, iii-d, iv-b
Correct answer: (B) i-c, ii-d, iii-a, iv-b
Explanation
The binary number 100000 equals 32 in decimal.
An 80 megabyte file over an 80 megabit link takes 8 seconds.
Compressing an 80 megabyte song by 90 percent leaves 8 megabytes, so 100 fit on an 800 MB disc.
The hexadecimal digit E equals 14 in decimal.
Each value follows from standard binary, hexadecimal and unit conversions.
Turning bytes into bits is the key step in the download timing.
