As it visually represents data as slices of a circle.

It highlighting the relative sizes of components.

Explanation

The given ratio is 16:24, which can be simplified as 2:3 (by dividing both numbers by 8).

To maintain the same ratio, we need to find the number that will maintain the 2:3 ratio with 72.

Let's multiply 72 by 2/3:

(2/3) × 72 = 48

So, the correct answer is: 48

The ratio 16:24 is equivalent to 2:3, and similarly, the ratio ? : 72 is equivalent to 2:3, which leads to the answer 48.

Explanation

Work = Force x Time

Since the work remains the same, we can set up a proportion:

18 workers x 26 days = x workers x 12 days

To solve for x, we can cross-multiply:

18 x 26 = x x 12

468 = 12x

Now, divide both sides by 12:

x = 468 / 12

x = 39

So, the correct answer is: 39 workers

Explanation

Number of boys who passed = 32% of 900 = 0.32 x 900 = 288

Number of girls who passed = 38% of 1100 = 0.38 x 1100 = 418

Total number of candidates who passed = 288 + 418 = 706

Total number of candidates = 900 (boys) + 1100 (girls) = 2000

Number of candidates who failed = Total number of candidates - Number of candidates who passed = 2000 - 706 = 1294

Total percentage of candidates who failed = (Number of candidates who failed / Total number of candidates) x 100 = (1294 / 2000) x 100 = 64.7%

So, the correct answer is: 64.7%
