Waec Model Questions Vol1 2021 Civic Education Question 37

A state assembly has 120 seats. Party X holds 45 seats, Party Y 30, Party Z 20, Party W 15 and Party V 10. To pass a constitutional amendment a two‑thirds majority (80 seats) is required. Only parties X, Y and Z support the amendment; W and V oppose it. Party X wishes to achieve the required 80 seats without forming a coalition with any other supporting party. There are five districts where Party X can contest by‑elections. The seats available in these districts are: District A - 6 seats, District B - 7 seats, District C - 8 seats, District D - 9 seats, District E - 10 seats. A party that wins a district takes all its seats. What is the minimum number of districts Party X must win to reach at least 80 seats on its own?
