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

List I

i.The hexadecimal value obtained when the two hexadecimal digits C and D are added together

ii.The denary (base-10) value of the binary number 00100100

iii.The number of seconds to transfer a 2 megabyte file over a 2 megabits per second internet connection

iv.If 1 gigabyte equals 2 to the power P, the value of P

List II

a.8

b.19

c.30

d.36

Ai-b, ii-d, iii-a, iv-c ✓ Correct

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

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

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

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

Explanation

In hexadecimal C is 12 and D is 13, and their sum 25 is written as 19 in hexadecimal, so i pairs with b.

The binary number 00100100 equals 32 plus 4, which is 36, so ii pairs with d.

A 2 megabyte file is 16 megabits, and over a 2 megabits per second link it transfers in 8 seconds, so iii pairs with a.

One gigabyte is 2 to the power 30 bytes, so the value of P is 30 and iv pairs with c.

Adding hex digits works like decimal but carries at sixteen instead of ten.

Hexadecimal 19 means one lot of sixteen plus nine, which equals decimal 25.
