If 5 women or 8 girls can do a work in 84 days. In how many days can 10 women and 5 girls can do the same work? | [
"82 days",
"72 days",
"22 days",
"32 days"
] | D | C
32 days
Given that 5 women is equal to 8 girls to complete a work.
So, 10 women = 16 girls.
Therefore 10 women + 5 girls = 16 girls + 5 girls = 21 girls.
8 girls can do a work in 84 days then 21 girls can do a work in (8*84/21) = 32 days.
Therefore 10 women and 5 girls can a work in 32 days | AquaRat_train |

An artist wishes to paint a circular region on a square poster that is 3.4 feet on a side. If the area of the circular region is to be 1/2 the area of the poster, what must be the radius of the circular region in feet? | [
"1",
"sqrt(2/pi)",
"sqrt(5.78/pi)",
"2/sqrt(pi)"
] | C | Area of the poster is 3.4x3.4 = 11.56
1/2 the area = 5.78
pi*r^2 = 5.78
r^2 = 5.78/pi
r = sqrt(5.78/pi) answer (E) | AquaRat_train |

First, look at the three values independently of their absolute value sign, in other words:

What is the greatest prime factor of 4^17 - 2^29? | [
"3",
"31",
"5",
"2"
] | B | I'm happy to help with this.
We know 4 = 2^2, so 4^17 = (2^2)^17 = 2^(2*17) = 2^34
That takes advantage of a law of exponents that says (a^n)^m = a^(n*m)
So, 4^17 - 2^29 = 2^34 - 2^29 = 2^(29 + 5) - 2^29 = (2^29)*(2*6) - 2^29 = (2^6 - 1) *(2^29)

I. At least 2 faces of the rectangular block are squares.
II. The volume of the block is 64. | [
"Both I and II are necessary to answer",
"I alone sufficient while II alone not sufficient to answer",
"II alone sufficient while I alone not sufficient to answer",

I gives, any two of l, b, h are equal.
II gives, lbh = 64.
From I and II, the values of l, b, h may be (1 ,1 , 64), (2 ,2 ,16), (4, 4, 4).
Thus, the block may be a cube or cuboid.

When distance is constant, speed is inversely proportional to the time
Hence, 2 × speed upstream = speed downstream
