Step-by-step explanation:
A job can be completed by 12 men and 16 women in 4 days. If 1 man takes 80 days to do that job alone, how many days can 1 woman do it alone
- Now one man one day’s work will be 1/80
- So 12 men and 15 women 1 day’s work will be ¼
- So for 1 day 1 man work will be 1/80
- So for 12 men it will be 12 / 80
- Therefore 16 women one day’s work will be ¼ - 12 / 80 = 1/10
- Now 1 woman one day’s work = 1/10 x 1/16
- = 1 / 160
- Therefore one woman can complete the work in 160 days
