Question

If 20 men consume a certain quantity of rice in 14 days, in how many days will 8 men consume the same quality of rice?

Answer 1

Answer:

35 days

Step-by-step explanation:

Let the required number of days = x

We construct the following table:

Attachment

Less men, more days so it is a case of inverse variation.

∴ 20 × 14 = 8 × x

⇒ x = $\sf{\dfrac{20 \times 14}{8}}$

⇒ x = 35

Hence, 8 men will consume the rice in 35 days.

Answer 2

Concept:

Inverse variation is the relationships between variables that are represented in the form of y = k / x.

Given:

We are given that:

20 men consume a certain quantity of rice in 14 days.

Find:

We need to find the number of days required for 8 men to consume the same quantity of rice.

Step-by-step explanation:

20 men can consume a certain quantity of rice in 14 days.

Let the number of days for 8 men be x.

ATQ:

20 × 14 = 8 × x

8x = 280

x = 35 days.

Therefore, the number of days required for 8 men to consume the same quantity of rice is 35 days.
