Neco Model Questions Vol1 2019 Government Question 5

A legislative committee consists of 15 members. Its rules state that a quorum of two‑thirds of the members must be present for the committee to conduct business, and any motion is adopted by a simple majority of the members who are present and actually vote (abstentions are not counted as votes). During a particular meeting, 6 members are absent, 2 members are present but abstain from voting, and the remaining members vote either for or against a motion. (a) Does the committee have a valid quorum? (b) What is the minimum number of votes in favour required for the motion to be adopted? (c) If the committee lacks a quorum, how many additional members must be present (whether they vote or not) to meet the quorum requirement?
