10 W =7 .. 5 W =14
10 C =7 .. 10C =14
1 day work of 5W+10C=1/14+1/14
1/14+1/14=1/7
Hence 7 days.
10 C =7 .. 10C =14
1 day work of 5W+10C=1/14+1/14
1/14+1/14=1/7
Hence 7 days.

10 W = 70 W.
10 Child 140 W.
1W =2 Child.
=> 5W+10 C= 5+5 Women = 7 days.
10 Child 140 W.
1W =2 Child.
=> 5W+10 C= 5+5 Women = 7 days.

How can we write 5 women's and 10 children's 1 day work is 5/70 and 10/140?

If ratio is 1:2 then (women * women working days/children)
i.e 10*7/10=7
i.e 10*7/10=7

W*d=c*d.
10*7W=10*14C.
W/c=2/1.
Now 10W*7=(5W+10C)*D,
140=20D,
D=7 days.
10*7W=10*14C.
W/c=2/1.
Now 10W*7=(5W+10C)*D,
140=20D,
D=7 days.

One more way to do this prob.
5* (1/70) +10* (1/140) =2/14=1/7=7 days.
5* (1/70) +10* (1/140) =2/14=1/7=7 days.

Short and fast
70w=140c
1w=2c
m1d1=m2d2
10X14=20Xd2
d2=7days ans.
70w=140c
1w=2c
m1d1=m2d2
10X14=20Xd2
d2=7days ans.

1 women= 2 childrens
so 5 women+ 10 children=10 women = 7days
so 5 women+ 10 children=10 women = 7days
