Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follows from the statements. Statements: All computers are laptops. All hard disks are pen drives. No pen drive is a keyboard. No computer is a hard disk. Conclusions: I. Some pen drives are not laptops. II. No keyboard is a computer. III. No hard disk is a laptop. IV. All pen drives are not keyboards.
Only conclusion IV follows
The least possible Venn diagram is:
Conclusions:
I. Some pen drives are not laptops → False (because all pen drives can be laptops as there is no direct relationship between these two)
II. No keyboard is a computer → False (it is possible as shown but is not definite as there is no direct relation)
III. No hard disk is a laptop → False (because all hard disks can be laptop as there is no direct relationship between these two)
IV. All pen drives are not keyboards → True (as no pen drive is keyboard implies all pen drives are not keyboards)
Hence, only conclusion IV follows.
