Answer 1

Let work done by 15 men in 9 days =w2w2

M1D1W1=M2D2W2M1D1W1=M2D2W2

18×301=15×9W218×301=15×9W2

= >W2=15×918×30=14W2=15×918×30=14

Remaining work = 1−14=341−14=34

16 women can complete the same project in 36 days, M1D1W1=M2D2W2M1D1W1=M2D2W2

= >16×361=18×D23416×361=18×D234

=>18×D2=34×16×3618×D2=34×16×36

D2=24days
