Ta1 + Ta2 + 2Ta3 =0 => constraint equation...
a1= acc of 2m, a2 = of 3m , a3 = of m.

accelerations are for masses from left to right
take a_{1}, a_{2}, a_{3}
2a1+a2+a3=0
mg-2t=ma1
2mg-t=2ma2
3mg-t=3ma3

from force eqn, express a1, a2, a3 in terms of T(tension) , m , g ...
put it into the constraint eq.
get value of T.
thence, find each of the accelerations :)

m=(19/5)
2m=(g/5)
3m=g/5
now it should be correct
time to polish my phy skills i guess

vishal check ur answer!
I am not sure that is the right answer :)
Your answer doesnot satisfy the constraint relation itself!

not so good ans.. i got some bad ans..
m= -19/29 g
2m = 17/29 g
3m= 21/29 g

where deccelerating???
'-' sign indicates that acceleration of m is upwards..
