Answer:
Step-by-step explanation:
M1 = 4
D1 = 6
M2 = 6
D2 = x (we've to find this)
<u><em>Since, it is an inverse proportion (more man takes less days for the work to complete and vice versa), so we'll write it in the form of</em></u>
M1 : M2 = D2 : D1
4 : 6 = x : 6
<u>Product of Means = Product of Extremes</u>
=> 6x = 4*6
=> 6x = 24
Dividing both sides by 6
=> x = 4 days
