ok lets try this.. can you find the total resistance of the circuit?

1/4 + 1/6 + 2 = total resistance

as a matter of fact no..
1/r = 1/r1+1/r2

can u show the working

first just find the parallel part of resistance..
1/r = 1/6+1/4
1/r = 5/12
agreed?

ok total resistance = 12/5 + 2

ok wt will A2 nd A3 be?

so find the drop on 3ohm resistor which is in series by V=IR

i dont get that part. now the current in a1 = 2.72 amps, so the voltage is 12v?

oh okay...so voltage = 8.18 V, then what do i do

ok means from 12V.. 3ohm took 8.18V.. how much voltage is left.?

3.81V

means both the resistors hve 3.81 V

yes.

because they are in parallel..

okay thanks...great help du knw anyother easy method of solving this
