\( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) are three tuning forks. Frequency of \( \mathrm{A} \) is \( 350 \mathrm{~Hz} \). Beats produced by \( \mathrm{A} \) and \( \mathrm{B} \) are 5 per second and by \( \mathrm{B} \) and \( \mathrm{C} \) are 4 per second. When a wax is put on \( \mathrm{A} \) beat frequency between \( \mathrm{A} \) and \( \mathrm{B} \) is
P \( 2 \mathrm{~Hz} \) and between \( \mathrm{A} \) and \( \mathrm{C} \) is \( 6 \mathrm{~Hz} \). Then, find the frequency of \( \mathrm{B} \) and \( \mathrm{C} \) respectively.
