Q. 10 men and 8 boys can do the same work as 4 men and 20 boys can do. Then how many men can do the work of 16 boys?

• 10m+8b=4m+20b
  1m=2b
  8m=16b
  so 8man =16 boy

• 10m+8b=4m+20b
  6m=12b
  1m=2b
  hence 8man needed to 16 boys works

• Here equate the one day work of both;
  i.e.,10M+8B= 4M+20B;
  6M=12B;
  THAT MEANS M:B= 1:2(Efficiency);
  M:B= 2:1(DAYS);
  16 BOYS = 8 MEN.....

• 8 men
  10 men + 8 Boys = 4men+20boys
  10-4 men =20-8 boys
  6 men=12 boys
  i.e. 1men=2 boys => 1boy = 1/2 man
  x men=16 boyz so x men =16*1/2 men
