on left block, Tension should be equal to sin component of weight.
T = m1gsin60
On right block, tension should also be equal to sin component of second block
T = m2gsin24
Equating
m1sin60 = m2sin24
m2 = m1sin60/sin24 = 2.13 m1
I was unsure, because text says 6.4kg and image says 6kg, so I am giving both values.
If m1 = 6.4kg ; m2 = 13.63kg
if m2 = 6kg ; m2 = 12.78kg
