aquarat_4516 | aquarat | A plane flies 420 miles with the wind and 350 miles against the wind in the same length of time. If the speed of the wind is 23 mph, what is the speed of the plain in still air? | [
"A)153mph",
"B)253mph",
"C)353mph",
"D)453mph"
] | B | The speed of the plane in still air = x miles/hour
The speed of the wind is 23 mph
Speed with the wind = (x + 23) mph
Speed against the wind = (x – 23) mph
Time = Distance/ Speed
According to the problem,
420/(x + 23) = 350/(x – 23)
420(x – 23) = 350(x + 23)
420x – 9660 = 350x + 805
420x – 350x = 8050 + 9660

aquarat_21823 | aquarat | 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. |

aquarat_33966 | aquarat | 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
