Apply kirchoffs current law at each junction of the circuit. i.e. current going in=current coming out.
See from left....2A+3A=5A (--> direction)
then 1A+2A=3A (upward dirn)
then 5A-3A=2A (downward dirn)
then 4A+2A=6A (rightward dirn)
then 6A+2A=8A=i (rightward dirn)............ans
 
Hope it helps :))
