Box of fruits can be loaded into a truck in 9 minutes by a
worker. And 8 boxes will fill a truck completely. How many trucks
can be loaded in 1 ½ hours if there are 16 men together.
a. 1
b. 2
c. 3
d. 0

• 1 worker can in 9 mins load 1 box
  1 worker can in 90 mins load (1*90/9)=10boxes
  16 worker can in 90 mins load (10*16)=160 boxes
  So no. of trucks needed=160/8=20 i think....

• @revathi on solving your eqn we get w2=160 not 16...so maybe 20 will be the answer wht do u think?????

• one man can load 8 boxes i.e, 1 truck in 72 min
  (9*8) so using formula (m1*t1)/w1= (m2*t2)/w2
  m1=1 t1=72 w1=8 m2=16 t2=90 (1&1/2 hrs) w2=?
  on sub on formula we get 16 boxes i.e., 2 truck.....

• one man can load 1 box in 9 minutes
  hence he can fill 1 truck in 1.12 hrs
  16 men can fill 16 trucks in 1.12 hrs
  remaining times is 18 minutes
  one can fill boxes in 18 min
  16 men can fill 32 boxes
  that is 4 boxes
  so total 20 boxes

• Number of minutes required to fill the truck completely by a Worker =9x8=72 mins
  Since 16 people are working together 16 people can fill 16 trucks in 72 mins
  now
  he asked for 1 and 1/2 hour i.e 90 mins
  90-72=18mins
  in 18 mins 16 people can fill 32 boxes in 4 trucks (9min-->1 box so that 16 mins--->2 boxes by one person
  so that 16 persons can fill 32 boxes in 18 mins so each truck 8 boxes for 32 boxes,32/8=4 trucks )
  
  so total no of trucks =16+4=20
