Question

Ghosh flies to South Africa from Mumbai non-stop. His flight leaves Mumbai at 5 am on 10\textsuperscript{th} December 2000 as per Indian Standard Time. What is the local time in South Africa when Mr. Ghosh reaches there?
Statement A
A. The average speed of the plane during the flight is 700 km/h.
Statement B
B. The flight distance is 10,500 km.

• A. The question can be answered by one of the statements alone but not by the other.
• B. The question can be answered by using either statement alone.
• C. The question can be answered by using both the statements together, but cannot be answered by using either statement alone.
• D. The question cannot be answered even by using both statements together.

Hint:

Time zone information is crucial for converting between local times of two locations.

Answer 1

The Correct Option is D

Even with both statements, we can find the flight duration ($= \frac{10500}{700} = 15$ hours) but cannot determine the local time in South Africa without knowing the time zone difference. Hence the question cannot be answered.
