If p and q are real numbers such that p>5 and q>4, what is the smallest integer larger than the product of pq?

a. 9
b. 10
c. 19
d. 20
e. 21

1 answer

5*4 = 20
so, 21 is the next largest integer

This assumes that p and q are close to 5 and 4. If p=40.27 and q=95.154, 21 is not the next largest integer.
