Literally sir being a dropper, in advance 2023 the question of doppler effect came and it was such an easy one which could be solved by watching your videos too but i had totally skipped those chapters so i skipped the question without even reading it once. THAT COSTED ME 6 MARKS. Made this mistake of leaving ques without giving it a try seriously costed me 30-40 marks in advanced. Otherwise i could have been in an iit and not a dropper.Sir i am writing this to speak my heart out because it pains to realise that i lost iit due to my own silly mistakes.

17:17 To make the question easier and solve without binomial approximation you can take the relative velocity of B wrt A. Now A is at rest and B has velocity of 2.5m/s. Simple fractions will be cancelled out and you only need to do (3005/599)*100. Which will give you 5.016*100 and you get 501.6 which we will round off to 502 Hz to match the answer.
