Given that,
Velocity of source, Vs = 5 x VO
Now, 
According to Dopper's effect we know that 
f subscript a space end subscript equals space f open square brackets fraction numerator v subscript s plus v subscript O over denominator v subscript s end fraction close square brackets i. e. comma space f subscript a space end subscript equals space f open square brackets fraction numerator v subscript s plus begin display style v subscript s over 5 end style over denominator v subscript s end fraction close square brackets equals space f cross times 6 over 5
Using the above relation we know that, the percentage increase in apperent frequency is
percent sign space i n c r e a s e space i n space a p p a r e n t space f r e q u e n c y equals fraction numerator f subscript a minus f over denominator f end fraction cross times 100 rightwards double arrow fraction numerator 6 over 5 f minus f over denominator f end fraction cross times 100 equals 20 space percent sign space space
