The arithmetic mean of two positive
P numbers \( a \) and \( b \) exceeds their geometric
W mean by \( \frac{2}{3} \) and the geometric mean exceeds their harmonic mean by \( \frac{6}{5} \). If \( a+b=\alpha \) and \( |a-b|=\beta \), then the value of \( \frac{10 \beta}{\alpha} \) is equal to
(1) 3
(2) 4
(3) 5
(4) 6
