a source of sound id traveling towards a stationary observer .The frequency of sound is heard by the observer is 25% more that the actual frequency.If the speed of sound is v,that of the source is
options:
1.v/4
2.v/5

Heloo ashu...the answer is v/4 bcoz :
let the first frequency be v1 and the second be v2.it is give that v2 is 25% of v1 i.e.
V2
