Question

10 men can complete a job in 16 days. How many days will it take if 8 men do the same job?
B. 20 days
A. 18 days
D. 22 days
C. 16 days​

Answer 1

Answer: 20 days

Step-by-step explanation: this is a case of inverse proportion

x1 * y1 = x2 * y2

10 * 16 = 8 * y2

let y2 be x

then

160 = 8x

x= 160/8

x = 20

so 8 men will take 20 days to complete the work

hope this helps you
