The question below is followed by two statements numbered I and II. Choose the option that describes whether the statements are sufficient to answer the question.
In which direction is the school from Anil’s house?
I. The school is 4 km to the west of the post office.
II. The bank is 4 km to the south of Anil’s house, and the school is 4 km to the west of the bank.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → The question can be answered by using one of the statements alone, but not by using the other statement alone.
To find the direction of the school from the house, the school must be placed with respect to the house.
Statement I alone:
It places the school with respect to the post office only; the post office is not placed with respect to the house: not sufficient
Statement II alone:
From the house, go 4 km south to the bank
From the bank, go 4 km west to the school
The school is 4 km south and 4 km west of the house, so it is south-west of the house: sufficient
Statement II alone answers the question, and statement I alone does not.
