Question

9. If 36 men can do a piece of work in 20 days, in how many days will 15 men complete
the same work?​

Answer 1

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

Answer 2

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