A man can load one box in 9 minutes. A truck can contain 8 boxes. If 16 men load for one and a half hour, how many trucks will be loaded?

• answer is 20 trucks loaded :
  1 person in 9 min can load 1 box
  1 person in 1 min can load 1/9 boxes
  16 person in 1 min can load 16/9 boxes
  16 person in 90 min can load 16*90/9=160 boxes
  
  now
  8 boxes in 1 truck
  so
  160 boxes comes under 20 trucks
  so answer is 20 trucks loaded

• m1*minutes/w1=m2*minutes/w2
  ->1*9/1=16*90/x
  ==>x=160
