Answer 2

Inverse proportion is the relationship between two variables such that the increase in one will cause a constant decrease in the other.

Given:

64 men = 20 days

Find the number of men needed to complete the work in 1 day:

20 days = 64 men

1 day = 64 x 20

1 day = 1280 men

Find the number of men needed to complete the work in 16 days:

1 day = 1280 men

16 days = 1280 ÷ 16

16 days = 80 men

Answer: 80 men
