The “competitive edge” of a baseball team is defined by the formula \(\sqrt{\frac{W}{L}}\), where W represents the number of wins, and L represents the number of losses. This year, the GRE All-Stars had three times as many wins and one-half as many losses as they had last year. By what factor did their “competitive edge” increase?
A. 1.5
B. 2
C. 2.5
D. 3
E. 3.5
Last Year:
Number of Wins = W
Number of Losses = L
Competitive Edge (Last Year) = \(\sqrt{\frac{W}{L}}\)
This Year:
Number of Wins = 3W
Number of Losses = 0.5L
Competitive Edge (This Year) = \(\sqrt{\frac{6W}{L}}\)
i.e. Competitive Edge (This Year) = \(\sqrt{6}\) x Competitive Edge (Last Year)
So, Option C
