80men
Step-by-step explanation:
64men=20days
x men=16days
(indirect propotion
64x20/16
1280/16
80 men
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
