QUESTION ONE
1 (a) Determination of the amount shared S
A + B + C + D = S
6:4:10:7 = K
K = S/27
6 + 4 + 10 + 7 =27
K = S/27
A X S/27 = 300 000,
6 X S/27 = 300 000
0.22222222S = 300,000
S = 300 000/.222222 S = 1 350 000FCFA
1(b) Determination of the shares of others
B ,s share = B,s ratio X K
K = 1 350 000/27 = 50 000
B = B,s ratio X K = 4 X 50 000 = 200 000FCFA
C = C,s ratio X K = 10 X 50 000 = 500 000FCFA
D = D,s ratio X K = 7 x 50 000 = 350 000FCFA
1(C) Determination of the number of customers brought by each agent
Total number of customers = 540
K = 540/27 = 20
A = 6 X 20 = 120 customers
B = 4 X 20 = 80 customers
C = 10 X 20 = 200 customers
D = 7 X 20 = 140 customers
QUESTION 2
2(a) : GRAPHICAL REPESENTATION
Total students per subject
= 20 + 50 + 25 + 15 + 30 + 40 = 180 students
