A box of fruits can be loaded in a truck in 9 minutes by a worker, and 8 boxes fill a truck completely. How many trucks can be loaded completely in 1 ½ hours if there are 16 men working together?

• If W=worker,B=box, M=man
  1W ,9M ,1B
  1W ,72M ,8B
  1W,90M ,10B
  16W,90M,160B=20 trucks

• 9 mins taken by a worker to load a box.there are 8 box, so total time is 8*9=72mins.
  1 worker takes 72 mins to load the truck.
  So in 1 mint he do 1/72 part of the work.so 16 men can do 16*1/72=2/9 part of the work.
  So 16 men can load a full truck in 4.5 mins.
  So 1truck is loaded in 4.5 mins.
  In 90 mins no.of trucks can be loaded=90/4.5=20.
  Ans.20 trucks.

• 1 man will load a box in 9 minutes
  16 men will load 16 boxes in also 9 minutes
  because they are working together
  Now
  in 90 minutes(1 & 1/2 hours)
  16 men will load 160 boxes in 90 min.
  as 8 boxes will fill one truck
  so 160 boxes will fill 20 trucks

• 1 1/2 hrs..90 mins
  1 men (90/9)=10 boxes
  16 men*10 boxes=160 boxes
  160/8=20 trucks
