Answer 1

Answer:

15 men do work in 8 days

Step-by-step explanation:

Answer: 15 men do work in 8 days

Then one man will do it in = 15×8

20 men will do it in = 120/20

= 6 days

Answer 2

Answer:

9 men

Step-by-step explanation:

In 9 days = 15 men plough the field

In 1 day = $\frac{15}{9}$ men plough the field

In 5 days = $\frac{15X5}{9}$ men plough the field

                = $\frac{25}{3}$ men plough the field

                = 8.25 men plough the field

A men can not be 0.25.

.: It will require 9 men to plough in 5 days.
