Conclusions: I. 20% Laptops can be Computers.

Solution

From Statement I. No Laptops is a Computers (E) → Probable conclusion → No conclusion. Hence conclusion I does not follow. Only a few Drive are Monitors (I) + Few Monitors are Laptops (I) → No conclusion. Hence conclusion II does not follow. From Statement II. Few Laptops are Monitors (I) + 100% Monitors are Computers (A) → Some Laptops are Computers (I). Hence conclusion I does not follow. Only Laptops is Drive → All Drive are Laptops and Drive can have negative relation with anyone. Hence conclusion II follows.   From Statement III. Only a few Laptops are Monitors (I) + [ All Computers are Monitors (A) → Conversion → Some Monitors are Computers  (I) → Probable conclusion → Some Laptops can be Computers (I). Hence conclusion I follows. No Drive is a Laptop (E) → Conversion → No Drive is a Laptop (E) → Conversion → Some Laptops are not Drive (O).  Hence conclusion II follows. From Statement IV. Only a few Laptops are Computers → Some Laptops are Computers (I). Hence conclusion I does not follow. Few Monitors are Laptops (I) + 40% Monitors are Drive (I) → No conclusion. Hence conclusion II does not follow.
