Question

12 men complete a work in 18 days in how many days the same work can be completed by 8 ?

Answer 1

Let the work completed by 1 man in 1 day be y.

So, the total work = 12 X 18 X y = 216y

12 men worked for 6 days, so total work completed = 12 X 6 X y = 72y

Remaining work = 144y

Total men now = 12 + 4 = 16

Work done in a day = 16y

Days required = Total work/Work in a day = 144y/16y = 9

Question: 12 men complete a work in 18 days in how many days the same work can be completed by 8 ?

Answer:

12 men = 18 days

8 men =  ? x days

So, 12x = 18 x 8

Therefore,  x = 18 x 8 / 12

         x = 12 days

THUS, 8 MEN CAN COMPLETE THE WORK IN 12 DAYS   ^_^
