On which day P is zero?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. D3.
For the one whose value of T will be 12, the value of P will be 0.
For D1, T = 17.30 - 05 : 44
⇒ T = 11 hours 45 minutes
For D2, T = 17 : 15 - 05 : 42
⇒ T = 11 hours 33 minutes
For D3, T = 17 : 36 - 05 : 36
⇒ T = 12 hours
Hence the required answer is D3.
