A source of sound is travelling with a velocity of 30 ms towards a stationary observer. If actual frequency of source is 1000 Hz and the wind is blowing with velocity 20 ms in a direction at 60∘C with the direction of motion of source, then the apparent frequency heard by observer is (speed of sound is 340 ms)
