If there are 10 people that can clean 10 floors by 10 mops in 10 days, in how many days can 8 people clean 8 floors with 8 mops?​

Answer 1

Answer:

By the given condition

10 men and 10 days mean 100 man-days are required to clean 10 floors with 10 mops.

So

1 floor requires 10 man-days to get cleaned.

Hence

To clean 8 floors you will require 80 man-days.

Thus

10 days are required to clean the 8 floors using 8 mops.

Answer 2

Answer:

Concept :

The time a person spends engaged in compensated work is referred to as working time. Personal housework, kid or animal care, and other unpaid tasks are not regarded as being part of the working week. The work week is governed by legislation in many nations, which may include establishing minimum daily rest intervals, yearly vacations, and a weekly maximum for hours worked. Working hours can vary from person to person, frequently depending on the economy, region, culture, lifestyle preference, and viability of the person's source of income.

Explanation:

M1 * D1 * W2 = M2 * D2 * W1

Here we dont concern about mop but we will consider work as floor

10 * 10 * 8 = 8 * X * 10

X =10 days
