1.  The product of two numbers is 192 and the sum of these two numbers is 28. What is the smaller of these two numbers ?
A. 12
B. 14
C. 16
D. 18
E. None of these

Answer: Option A

Explanation:

Let the number be x and (28 - x). Then,
x(28 - x) = 192
<=> X2 – 28x + 192 = 0
<=> (x - 16) (x - 12) = 0
<=> x = 16 or x = 12.
So, the numbers are 16 and 12.
