Answer 1

Answer:

10 days

Step-by-step explanation:

Answer 2

In the above question it is given that,

Fifteen men can complete  the construction of a wall in 12 days,

Now we have to find out the numbers of day required by 18 men to complete the construction of a wall.

We can solve the equation by traditional unitary method.

I.e. $15*12=18*X$

where x is the number of days,

Thus by solving the equation we get,

$15*12=18*X\\180=18X\\\frac{180}{18} =X\\\\10=X$

further we can write it as ,

$X=10$

Hence the numbers of days required by 18 men to complete a wall is $10$ days.
