A piece of work can be done by 16 men in 8 days working 12 hours a day. How many men are needed to complete another work, which is three times the first one,in 24 days working 8 hours a day?
a)24 men
b)29 men
c)20 men
d)30 men

• a)24 men
  16*8*12=1536
  3 times the work=3*1536=4608
  4608/24*8=576/24=24 men

• Apply the MHD rule : (M1*H1*D1)/w1=(M2*H2*D2)/w2
  (16*12*8)/1=(M2*8*24)/3( here w2 is 3 as the work is three times the first one)
  Solving , we get M2 =24 days
  Thus, the answer is 24 days
