Explanation

Statement of the given problem,

A mixture of 17 parts of A, 3 parts of B, and 4 parts of C weigh 72 ounces. How many ounces of substance B are in this mixture?

From above data we get following relations,

A/17 = B/3 = C/4 = k (say) …… (1)

A + B + C = 72 …… (2)

From (1) & (2) we get,

17*k + 3*k + 4*k = 72 or k = 72/24 = 3 …… (3)

From (1) & (3) we get,

B = 3*3 = 9 (ounces) [Ans]

Explanation

1 pound is equal to 16 ounces

or

1 pound is equal to 453.6 grams

1 pound is equal to 0.45359 kilograms

Explanation

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x

S.P. of x articles = Rs. 20

Profit = Rs. (20 - x)

∴20−xx×100=25⇒2000−100x=25x125x=2000⇒x=16

Explanation

The other numbers in the list are all prime numbers, whereas 81 is a composite number (3^4).

Explanation

Explanation

If each side of the cube is doubled in length, the new side length will be twice the original side length. Since the volume of a cube is proportional to the cube of the side length, the new volume will be:

New volume = (2 × original side length)^3

Since the original volume is 8 cubic meters, we can find the original side length by taking the cube root of 8:

Original side length = ∛8 = 2 meters

Now, we can find the new volume:

New volume = (2 × 2)^3 = (4)^3 = 64 cubic meters

So, the correct answer is: 64
