Gce Model Questions Vol1 2022 Civic Education Question 26
Practice objective / multiple choice question 26 from the 2022 Gce Model Questions Vol1 Civic Education examination.
In a region there are four ethnic groups A, B, C and D. Historical data show the average annual number of violent incidents between each pair of groups as follows: AB = 12, AC = 8, AD = 5, BC = 10, BD = 7 and CD = 9. The government can sign bilateral peace agreements. Each agreement reduces the incidents for that pair by (40\%\) and reduces the incidents for any other pair that shares a common group with the agreed pair by (10\%\) (the reduction is multiplicative if a pair is affected by several agreements). What is the minimum number of bilateral agreements that must be signed so that the total expected incidents per year do not exceed 30?
