If p and q are two non zero numbers and 18 p q ... - JAMB Mathematics 2010 Question
If p and q are two non zero numbers and 18 (p + q) = (18 + p)q, which of the following must be true ?
A
p ˂ 1
B
p = 18
C
q ˂ 1
D
q = 18
correct option: b
18(p+q) = (18+p)q
18p + 18q = 18q + pq
By comparison
18p = 18q or p = q
Again, 18q = pq or 18 = p which is required
18p + 18q = 18q + pq
By comparison
18p = 18q or p = q
Again, 18q = pq or 18 = p which is required
