There's a relatively easy way to solve problems of this nature. You determine the contribution made if the only contributor is the one that contributes the least.

A chicken has the least number of feet, so 24 chickens will contribute 48 feet.

Now, you consider the change in contribution made by substituting a larger contributor. Each pig that replaces a chicken will add 2 feet to the total.

Consider how many feet need to be added, and thus how many larger contributors are needed. 80 -48 = 32 feet need to be added, so 32/2 = 16 of the animals need to be pigs.

There are 16 pigs and 8 chickens.

Answer:

B. 200 doses

Step-by-step explanation:

Given,

1 dose is required for 100 mg,

Since, 1 mg = 0.001 g,

⇒ 100 mg = 0.1 g

⇒ 1 dost is required for 0.1 g,

Thus, the ratio of doses and quantity ( in gram ) is $\frac{1}{0.1}=10$

Let x be the doses required for 20 grams,

So, the ratio of doses and quantity is $\frac{x}{20}$

$\implies \frac{x}{20}=10$

$\implies x=200$

Hence, 200 doses can be obtained from 20 grams of the drug.

Option 'B' is correct.

White raven [17]

Answer:

24.38 meters to the nearest hundredth.

Step-by-step explanation:

1 foot is approximately 30.48 cm.

So 80 feet = 80 * 30.48 cm.

In meters this is (80 * 30.48) / 100

= 24.38 m.
