Question

If 18 men can finish cleaning a ground in 20 days then 15 men will take how many days to do the same work

Answer 1

Answer:

24

Step-by-step explanation:

18 men finish cleaning the ground in 20 days

1 men finish cleaning the ground in 20×18

15 men finish cleaning the ground in 20×18÷15 = 24

Answer 2

18 men can clean the ground in 20 days

∴ 1 man can clean the ground in(20×18) days [∵ seems it is in inverse proportion]

∴ 15 men can clean the ground in (20×18/15) [∵ since if the number of people increase then the number of days will decrease.

=(4×18/3)

=(4*6)

=24 days

So, they can finish cleaning the ground in 24 days.
