Question

if it takes four men to dig a land in 6 days.how many days will it take 6 men to build that same land.​

Answer 1

Answer:

$\boxed{4 days}$

Step-by-step explanation:

M1 = 4

D1 = 6

M2 = 6

D2 = x (we've to find this)

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

M1 : M2 = D2 : D1

4 : 6 = x : 6

Product of Means = Product of Extremes

=> 6x = 4*6

=> 6x = 24

Dividing both sides by 6

=> x = 4 days

Answer 2

Answer:

4 days

Solution,

____________________________

Men ------------------------------ Days

4 ------------------------> 6

6 ------------------------> X (suppose)

_____________________________

In case of indirect proportion,

4/6= 6/X

or, 6*X= 6*4 ( cross multiplication)

or, 6x= 24

or, 6x/6= 24/6 ( dividing both sides by 6)

x= 4 days

Hope this helps...

Good luck on your assignment..
