Which of the following options best describes the number of vacant houses in Row-2?
Explanation:
Consider the solution to first question of this set.
In row 2, B2 and E2 are definitely vacant.
Out of D2 and F2, at least one is occupied, hence either 1 is vacant or 0 are vacant.
Case 1: One of D2 or F2 is vacant. ∴ We have B2, F2 and (D2 or F2), i.e., 3 houses vacant in row 2.
Case 2: None of D2 or F2 is vacant. ∴ We have B2 and F2, i.e., 2 houses vacant in row 2.
∴ In row 2, either only 2 houses are vacant or 3 houses are vacant.
Hence, option (d).
