A speeding motorcyclist sees traffic jam ahead of him. He slows down to $\displaystyle 36$ km/hour. He finds that traffic has eased and a car moving ahead of him at $\displaystyle 18$ km/hour is honking at a frequency of $\displaystyle 1392$ Hz. If the speed of sound is $\displaystyle 343$ m/s, the frequency of the honk as heard by him will be :
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle 1412$ Hz
