Match List–I and List–II and select the correct group of matching.
List–I
P. RAM
Q. CPU Speed
R. Monitor
S. CD–ROM Speed
List–II
1. Hertz
2. MB
3. Bytes/Sec
4. Inch
1
(P,2), (Q,1), (R,4), (S,3)
2
(P,1), (Q,2), (R,3), (S,4)
3
(P,3), (Q,4), (R,2), (S,1)
4
(P,4), (Q,3), (R,1), (S,2)
✓ Solution
RAM → MB
CPU Speed → Hertz
Monitor → Inch
CD–ROM Speed → Bytes/Sec
Hence the correct match is $(P,2), (Q,1), (R,4), (S,3).$
