Question

In the circuit shown below each resistor is 100 Ω. The current flowing through the 25 V
battery is 200 mA, and the current flowing through the 10 V battery is 150 mA.
The current through the resistor in the center is:
(a) 150 mA from a towards b.
(b) 150 mA from b towards a.
(c) 50 mA from a towards b.
(d) 50 mA from b towards a.
(e) 0 mA.

Please see image below for curcuit.

Answer is (c), but I am unsure exaclty why..

 

Please show full work!

 

Thank you!
