Please see the attachment.
This type of circuits can be solved using Kirchaff's laws.
The first law says that at any junction in the circuit the net current is zero or the total inward current is equal to the total out ward current and hence applying this law at the junction point B we have
I1 + I2 = I3 ---------- (1)
The second law says that the total drop in potential in a closed loop is equal to the total EMF in the circuit
Or
Where E is the EMF of a cell, I is the current and R is the ...
