What is unitary method?

The method in which first we find the value of one unit and then the value of the required number of units is known as the Unitary Method.

According to the given question.

Number of floors in each house = 4

Number of appartments in each floor = 4

Number of doors in each apartment = 4

Number of hi-nges in each door = 4

So,

The number of doors in four house

= 4 × 4 × 4

= 64 doors  

( unitary mehod)

Therefore, the total number of hi-nges in four house

= total number of door × 4                   (unitary method)

= 64 × 4

= 256

Hence, there are total 256 hi-nges in four houses.
