GATE | GATE-CS-2016 (Set 2) | Question 8

All hill-stations have a lake. Ooty has two lakes.

Which of the statement(s) below is/are logically valid and can be inferred from the above sentences?


(i) Ooty is not a hill-station.
(ii) No hill-station can have more than one lake. 

(A) (i) only
(B) (ii) only
(C) both (i) and (ii)
(D) neither (i) nor (ii)


Answer: (D)

Explanation:
Given statement doesn’t say that –



“All hill-stations have a lake” but any place having a lake is surely a hill station.

—> Ooty may or may not be a hill station
Hence (i) is false

—> Here, it is not a compulsion that a place need to have exactly one lake to be a hill station.
Hence (ii) is also false
