1. Answer:

   56

   Step-by-step explanation:

   Description for Correct answer:

   Given, M1 = 120, M2 = 120-x,

   D1 = 64, D2= 124-64= 60

   W1 = 2/3 and W2=1/3

   According to the formula,

   M1*D1/W1= M2*D2/W2

   => 120×64÷2/3=(120−x)×60÷1/3

   => 120×64/2×60=(120-x)

   => (120-x)=64

   x=120-64=56

   Now, 56 men can be discharged to finish the work in time.
