Match List I (Statement) with List II (Value) and choose the correct answer from the options given below.

List I

i.The number of bits that make up a byte

ii.The base-10 (denary) value of the binary number 001111

iii.The number of minutes to upload a 75 megabyte file at 2 megabits per second upload speed

iv.If there are 2 to the power P bytes in a kilobyte, the value of P

List II

a.5

b.8

c.10

d.15

Ai-a, ii-b, iii-c, iv-d

Bi-b, ii-d, iii-a, iv-c ✓ Correct

Ci-c, ii-d, iii-a, iv-b

Di-b, ii-a, iii-d, iv-c

Correct answer: (B) i-b, ii-d, iii-a, iv-c

Explanation

A byte is made up of 8 bits, so i pairs with the value 8, which is b.

The binary number 001111 equals 8 plus 4 plus 2 plus 1, which is 15, so ii pairs with d.

A 75 megabyte file equals 600 megabits, and at 2 megabits per second that takes 300 seconds, which is 5 minutes, so iii pairs with a.

A kilobyte is 1024 bytes, equal to 2 to the power 10, so the value of P is 10 and iv pairs with c.

Reading the binary place values from the right as 1, 2, 4, 8 makes the base-10 conversion quick.

Multiplying bytes by 8 to reach bits is the essential step when turning a file size into a transfer time.
