Easiest way to solve this question is through options:
a) If 600 voted for A and 1200 voted for B then
Before influencing, A – 600 + 600 = 1200, B – 1200 – 600 = 600(As half of B’s vote were through influencing)
Before kidnapping, A – 1200 + of 1200 = 1800 (As 1/3 of A’s voters were kidnapped which is half of the 2/3 that remained)
Thus, total voter initially = 1800 (A) + 600 (B) = 2400
Thus option a) fits the scenario given in the question completely.
Therefore,
Answer – (a)
Correct Answer: 600(A), 1200(B)
