Question

i) 18 men can complete a task in 12 days. How many more men should be employed to complete the same
task in 9 days? ​

Answer 1

Step-by-step explanation:

∴18 men can do a work in 12

∴1 " " " " " " 12/18

∴9 " " " " " " 12/18*9 = 6 people

∴ 6 People can do a task in 9 days

Answer 2

Step-by-step explanation:

days taken to complete the task by 18 men = 12

work done by 18 men in one day = 1/12

work done by 1 man in one day =( 1/12)*1/18

= 1/ 216

so, work done by 1 man in 9 days= 1*9/216

= 1/24

so, 24 men will do the work in 9 days.

then, 6 more men should be employed to complete the task in 9 days.
