tension in string attached to 2kg block is T                             lets assume acceleration of 6,2,3 kg blocks is a1,a2,a3 respectively.
tension in string attached to 3kg block is T
=> tension in string attached to 6kg block is 2T
therefore 
equation of 6kg block is 60-2T=6a1....(1)
equation of 2kg block is T-20=2a2.....(2)
equation of 3kg block is 30-T=3a3.......(3)
from constraint relation we get a1+a3=a2(4)
therefore we have got 4 equations for 4 variables , solve them and find the answere.
I think solving is easy an need not be done here .
