Answer:

32 days

Step-by-step explanation:

Men. Hours. Days

30. 6. 56

45 7. X

More men less hours: inverse relation, switch the fraction 30/45 to 45/30.

More hours less days: inverse relation, 6/7 switch to 7/6.

(45/30)*(7/6) = 56/x

7/4 = 56/x ( cross multiplication)

7x = 4*56

x = 224/7

x = 32
