choices are 
a) 12 v
b) 11.04 v
c) 10.44v
d) 8.54v

Draw the circuit with load of 12 A and I, with V across the load.
You have two unknowns, I, V and therefore need two equations to solve.
Use circuit analysis for one and P = IV for the other, have a good time calculating.

anonymous · Answer

The voltage across both parallel loads will be 10.44 v or 0.96 v either by solving the quadratic equation. Hence option (c) is correct.

I hope I could post the image of solution on paper for illustration.
