Question
28. (4) 16 men ( =20 ) women ( Rightarrow quad 4 mathrm{men}=5 ) women
( therefore 28 mathrm{men} ) and 15 women ( =28 times frac{5}{4}+15 )
( =50 ) women
By ( M_{1} D_{1}=M_{2} D_{2} )
( 20 times 25=50 times D_{2} )
( therefore quad D_{2}=frac{20 times 25}{50}=10 ) days

28. If 16 men or 20 women can do a piece of work in 25 days. In what time will 28 men and 15 women do it? (1) 142 days (3) 182 days (2) 33. days (4) 10 days days
