Answer:
48 days
Step-by-step explanation:
let one man take x days to complete the work
therefore 1 man's 1 day's work= 1/x
36 men's 1 day's work= 36/x
its given that 36 men take 20 days to complete a work, therefore 36 men's one day's work=1/20
36/x=1/20
x=36X20
x=720 days
therefore 15 men take 720/15 days
=48 days
hope this helps pls mark as brainliest

36 men = 20 days
15 men = (?) days
= 36 x 20 / 15
= 720 / 15
= 48 days
15 men = (?) days
= 36 x 20 / 15
= 720 / 15
= 48 days
