A tuning fork `P` of unknows frequency gives `7` beats in `2` seconds with another tuning fork `Q`. When `Q` runs towards a wall with a speed of `5 m//s` it gives `5` beats per second with its echo. On loading `P` with wax, it gives `5` beats per second with `Q` . What is the frequency of `P`? Assume speed of sound = `332 m//s` .

A tuning fork P of unknown frequency gives 7 beats in 2 seconds with another tuning fork Q is moved towards a wall with a speed of 5 m//s , it gives 5 beats per second for an observer located left to it. On filling, P gives 6 beat per second with Q . The frequency (in Hz) of P is given by (80 xx alpha)+beta, (alpha, beta in I, 0 le alpha, beta le 9) then find the value of alpha + beta . Assume speed of sound = 332 m//s .
