Four wolves, Wolverine, Man-hunter, Blue-wolf, and Jasmine, caught rabbits for their evening meal. If Man-hunter caught 3 more rabbits than Blue-wolf did, Jasmine caught 3 less than Wolverine did, and Wolverine caught 1 more than Man-hunter did, how many more fewer rabbits did Blue-wolf catch than Jasmine? Choose the correct choice from the following answers:  A) -3  B) -2  C) -5  D) -12  E) -1
In this word problem, the first key is to turn the story into equations:   Man-hunter caught 3 more than Blue-wolf did: M = 3 + B   Jasmine caught 3 less than Wolverine did: J = W - 3   Wolverine caught 3 more than Man-hunter did: W = 1 + M   Then, in classic GMAT style, the problem doesn't ask you to solve for a single variable, but instead to solve for the difference between B and J (how many more rabbits did Blue-wolf catch than Jasmine did?). This means that your goal is to get the equations in terms of B and J so that you can solve for the expression B - J.   Taking the first equation and solving for B, you have B = M - 3.   Taking the second equation and solving for J you have J = W - 3, and then with the third equation you can replace W with 1 + M so that both B and J are in terms of M: J = (1 + M) - 3.   So if B = M - 3 and J = M - 2, then:   B - J = (M - 3) - (M - 2)   B - J = M - 3 - M + 2 (remove the parentheses by distributing the multiplication)   B - J = -1, so the answer is -1.
