Answer:
B receives 62000 votes
C receives 47000 votes
Step-by-step explanation:
Let C be the vote for candidate C
Let B be the vote for candidates D
Let the total vote be T. Therefore,
C + B = T (1)
But C receives 15000 votes fewer than B ie
C = B —15000 (2)
Total votes, T = 109000
Substituting the value of C and T into equation 1
C + B = T
B — 15000 + B = 109000
Collect like terms
B + B = 109000 + 15000
2B = 124000
Divide both side by the coefficient B i.e 2
B = 124000/2
B = 62000
Putting the value of B into equation 2;
C = B —15000
But B = 62000
C = 62000 — 15000
C = 47000
B receives 62000 votes
C receives 47000 votes
