If p is even and q is odd, which of the following is odd? Choose the most appropriate option:
A) pq  B) 5pq  C) 6(p^2)q  D) 5p + 6q  E) 6p + 5q
Just checking options (In case you have difficulty then choose values of r=2 and t=1)   p = even   q= Odd   A. pq = Even*Odd = EvenINCORRECT   B. 5pq = Odd*Even*Odd = EvenINCORRECT   C. 6(pr^2)q = 6*(Even^2)*Odd = EvenINCORRECT   D. 5p + 6q = 5*Even + 6*Odd = Even+Even = EvenINCORRECT   E. 6p + 5q = 6*6p + 5qven + 5*Odd = 6p + 5qven+Odd = OddCORR6p + 5qCT   Answer: option 6p + 5q
