Given that 5 women is equal to 8 girls to complete a work. So, 10 women =
16 girls. Therefore 10 women + 5 girls = 16 girls + 5 girls = 21 girls.
8 girls can do a work in 84 days then 21 girls can do a work in (8*84/21) = 32 days.
Therefore 10 women and 5 girls can a work in 32 days

5W=8G, Thus 1W=8/5G
Now, 10W and 5G is equivalent to 21G
8 girls can complete the work in 84 days
21 girls can complete the work in 84/21*8=32 days

5W=8G=1/84
1W=1/420=1/(84*5)
10W=10/(420)
1G=1/(84*8)
5G=8/(84*8)

10W+5G=10/(84*5)+5(84*8)
=(80+25)/(84*5*8)
=105/84*5*8
=1/32
so 10W and 5G can do the work in 32 days.........
