How many women can complete the work in 5 days?

1 women can complete the work in (10 * 8) days= 80 days. 1 child can complete the work in (16 * 10) days= 160 days. 1 women 1 days work = 1/80 , 1 child 1 days work= 1/160. (10 women +12 children) 1 days work = ( 10 * 1/80 +12 * 1/160) = ( 1/8 + 3/40 ) = 8/ 40 = 1 /5. ∴ 10 women and 12 children will finish the work in 5 days.
