Answer 2

Answer:

4 men

Step-by-step explanation:

This is an indirect proportional question where if a value rises the other decreases or vise versa .

In indirect propotions , the product remains constant such as 2 x 3 = 6 = 1 x 6 .

So if u take it as an proption , u get

6 men : 12 days :: ? men : 18 days

As the product remains constant , check the product of first two numbers here :

6 x 12 = 72 .

So the other one shld also be

? x 18 = 72

next , 72/18 = 4 .

So there are 4 men .
