Loop BDCB :- 3×i1 + 4×(i1+i3)  = 7×i1 + 4×i3 = 6 .....................(1)
Loop BACB:-    3×i2 - 3×i3 = 6 ....................................................(2)
Loop BADB    -6×i3 + 3×i1 = 0 or i1 = 2×i3 .................................(3)
 
solving the above eqns., we get i1 = 2/3 A ,   i2 = 7/3 A ,  i3 = 1/3 A 
 
Current drawn from battery, i = i1 + i2 = (2/3) + (7/3) = 3 A
