In figure 1 V B – V A = 12 V and in In figure 2 V A – V B = 15 then choose the correct option. If same battery is used in both the circuits. (a) ε = 12.6 V (b) ε = 13.2 V (c) ε = 13.6 V (d) ε = 14.0 V

In figure 1    VB – VA = 12 V and in
    
In figure 2    VA – VB = 15 then choose the correct option.

Net potential difference = E – i r
Using this concept for the two circuits, you will get two equations in variable terms (E, e.m.f.) and internal resistance.
It wouls be like equations in two variables, and then calculate the value of E.M.F. connected.

Good Luck...................................................................
