Two cars moving in opposite directions approach each other with speed of $\displaystyle 22$ m/s and $\displaystyle 16.5$ m/s respectively. The driver of the first car blows a horn having a frequency $\displaystyle 400$ Hz . The frequency heard by the driver of the second car is [velocity of sound $\displaystyle 340$ m/s] :
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle 448$ Hz
