In a survey about potential presidential candidates A and B, 35% of the public like A and 53% like B. If the percentage of the public who like one candidate only is twice the percentage of the public who like both candidates, then what is the percentage of the public that like neither?
[ "A)27%", "B)34%", "C)41%", "D)22%" ]
B
Let x be the percentage of people who like both. Then the percentage of people who like only 1 but not both is 2x. 35% + 53% = 2x + 2(x) because the percentage who like both are counted twice. Then x = 22% and 2x = 44% 100% = 22% + 44% + Neither Neither = 34% The answer is B.

If x = 6^36 and x^x = 6^k, what is k?
[ "A)6^36", "B)6^38", "C)6^72", "D)6^216" ]
B
Solution: We know that x=6^36 which implies x^x = (6^36)^(6^36) = 6^(36 * 6^36) [because (x^y)^z = x^(y*z))] so 6^(6^2 * 6^36) = 6^(6^(2+36)) [because x^a * x^b = x^(a+b)] therefore x^x = 6^(6^38) Given that x^x=6^k so 6^(6^38) = 6^k Since the base is same the exponent will also be same therefore k = 6^38 Answer:B
