Neco 2018 Government Question 32

In a federal election, a political party must obtain at least \(5\%\) of the total valid votes nationwide to be allocated seats in the National Assembly, unless it wins at least one constituency seat, which exempts it from the threshold. The election produced 80 000 000 valid votes. Party X received 4 800 000 votes and won 2 constituency seats. Party Y received 3 900 000 votes and won no constituency seats. Party Z received 2 500 000 votes and also won no constituency seats. Parties may form a coalition; a coalition is eligible for seat allocation only if the combined vote share exceeds \(10\%\). Assess which parties (or coalitions) are eligible for seat allocation.
