Neco 2018 Government Question 33

A country with a 100‑seat legislature uses a parallel electoral system: 60 seats are filled by first‑past‑the‑post (FPTP) in single‑member constituencies, and the remaining 40 seats are allocated to parties by the D'Hondt method with a \(5\%\) threshold. Four parties obtain the following nationwide vote shares and constituency seats:\n\n- Party A: \(42\%\) of the vote, 30 constituency seats;\n- Party B: \(28\%\) of the vote, 20 constituency seats;\n- Party C: \(18\%\) of the vote, 10 constituency seats;\n- Party D: \(12\%\) of the vote, 0 constituency seats.\n\nUsing the D'Hondt method, determine the total number of seats each party holds after both tiers are combined.
