Life expectancy is defined by the formula \(\frac{2SB}{G}\), where S = shoe size, B = average monthly electric bill in dollars, and G = GRE score. If Melvin’s GRE score is twice his monthly electric bill, and his life expectancy is 50, what is his shoe size?
A. 42
B. 44
C. 46
D. 48
E. 50
I couldn't stop laughing, what a weird question
Anyways,
Life expectancy = \(\frac{2SB}{G}\)
Its given that G = 2B, when Life expectancy = 50
Therefore,
50 = \(\frac{2SB}{2B}\)
50 = S
Hence, option E
