The product of Tom's age in years, and half of Jerry's age in years, is 54. If Jerry is 3 years younger than Tom is, Jerry is how many years old?	Choose the correct choice from the following: A) 6 B) 8 C) 9 D) 10 E) 12
Let Tom's age be x &amp; Jerry's age be y.   x * y/2 = 54   x * y = 108   Also, given y=x-3   Substituting x^2 - 3x = 108   Factoring, we get the ages to be 12 and -9.   Since age cannot be negative, Tom's age is 12.   Jerry's age therefore must be 9   Ans :(Option 9)
